I am looking for a verb to describe the action of a good guy becoming a bad guy. There is a word for it in my mother language, but I am not sure if there is a word for it in English.

The verb, which could be literally translated as 'become bad, turned into a bad guy'. an example would be:

He used to be a good cop, but now he___, mingles with the gangsta on the street, sad thing.

update: thanks everyone for your answers and comments. it seems a word to describe this behavior of people working in law enforcement is unanimous, but a word to describe this behavior that includes ordinary folk seems remains controversial.

    Not a verb, but tarnished. – Myridium Jun 22 '17 at 08:27
  • A word to describe this behavior that includes ordinary folk will remain controversial because everyone has their own moral code. Corruption is in the eye of the beholder unless there is a job description. For instance, Hank Voight, on the TV show CPD. At first glance he seems bad because he mingles with the crooks, but that's how good cops get stuff done. Remove this whole god cop / bad cop thing if you want to talk about the rest of us. Further adding to the confusion, IMO, (good cop / ) "bad" cops aren't necessarily crooked cops. – Mazura Jun 22 '17 at 13:19

One could also use the word turned; e.g.:

He was once an honest politician, but having been exposed to the crime syndicates for so long, now he's been turned.

to corrupt

  • to destroy the integrity of; cause to be dishonest, disloyal, etc., especially by bribery.
  • to lower morally; pervert
  • to alter for the worse; debase.

In your sentence it could be used as:

...but now that he was corrupted, he mingles with...

Other options include:

  • debase
  • infect
  • pervert
  • taint
  • warp

    Based on my experience when reading fictions, the genre "corruption" is the exact term that describes OP's situation. – Andrew T. Jun 24 '17 at 08:28

For a wrestling reference you could use turned heel. In professional wrestling 'good guys' are 'babyfaces' (more commonly just called 'faces'), and the 'bad guys' are heels. When a wrestler changes it's called 'turning'. Thus, a good guy going bad in wrestling is 'turning heel'.

Your cop has gone rogue.

"Going rogue" commonly means defying orders or convention to the degree that one is assumed to have left the organization or movement. He might never be a good cop again.

  • 32
    I feel like going rogue has less of a "bad guy" connotation, and more of a "he pursues his goals outside of the regulations set by his organization," which could mean bad (as in "bad-guy"), but doesn't necessarily. – AmagicalFishy Jun 20 '17 at 18:06

    This feels like a very American English expression - I'd like to see speakers of other dialects chime in on how common it is in their dialect. (We do hear it in Canadian English, but our English has a lot of AmEng terms.) – Jim MacKenzie Jun 20 '17 at 19:29

    Rogue used to describe a cop definitely conveys that the cop has become a criminal, it doesn't just mean "unconventional methods." – barbecue Jun 20 '17 at 19:51

    Axel Foley went rouge but he was not a "bad cop". Breaking the law doesn't make you a bad cop. Only moral bankruptcy can do that. – Mazura Jun 20 '17 at 23:33
  • 2
    @Mazura Be careful! Rouge is an entirely different word (a shade of red, a type of makeup for the cheeks, or the single point score allowed in Canadian football) than rogue. The former is pronounced something like "roozh". – Jim MacKenzie Jun 21 '17 at 13:22

    "Gone rogue" does not imply criminal activity. In fact, it could even mean that your cop refuses to engage in criminal activity when everyone else in is department has been corrupted. See http://www.urbandictionary.com/define.php?term=Gone%20Rogue and https://www.merriam-webster.com/words-at-play/were-going-rogue – Solomon Slow Jun 25 '17 at 22:46

Break bad: (colloquial, especially Southern US and Midwestern US, of a person) To go bad; to turn toward immorality or crime

E.g. But somehow he broke bad when he was just a yearling boy, started running around at night with a bad crowd, drinking beer and wine, and fighting and getting in all kinds of trouble and wouldn't go to school.

    I would say that, TV series titles aside, this is likely not to be understood by many listeners. – Muzer Jun 20 '17 at 16:57
  • 36
    Midwestern US here (raised in Chicago suburbs); I've never heard this phrase outside of that TV show's title. Before even reading Muzer's comment, when I saw this answer I was like, "Oh, so that's what that means?" – Izkata Jun 20 '17 at 17:50
  • 1
    If anything, I think the show's title being so familiar adds to the credibility of this being the preferred answer. Perhaps it was not a particularly common term before, but it certainly has much wider adoption now as a result of the series. I may have heard it fewer than five times in my life before the show aired, but I am surprised that anyone from the US would have been totally unfamiliar with the term - especially after knowing about the show. – Darren Ringer Jun 20 '17 at 20:01

    @DarrenRinger the phrase itself is now more widely recognized, but I don't think its usage in this sense is. – Kevin Jun 20 '17 at 21:16

    @called2voyage I would wager that most who hear the term "breaking bad" think of the TV series first, then those who have seen the series recall the meaning of the phrase by remembering the ONE scene in the series where it was used in a sentence. – vijrox Jun 21 '17 at 19:32
  • 2
    @vijrox The meaning is not hard to figure out if you know a one-liner description of the point of the show. I have never watched it and didn't know the meaning of the phrase before it was used as the title of the show. – called2voyage Jun 21 '17 at 19:33

    Until the tv show, I'd never seen anyone use the phrase "break bad". Since the tv show, I've seen tons of people use the phrase "break bad": 100% of the time, as a synonym for "make meth". – neminem Jun 21 '17 at 23:43

  • FWIW, I've never heard it used as a synonym for "make meth". I am surprised that so many people appear to be confused about a phrase that most definitely existed before the show, and in fact answers the question perfectly well. I guess this is a glimpse into why regional dialect stays so regional - apparently it is nonsense to everyone else. – Darren Ringer Jun 23 '17 at 12:56
  • Southwestern US, I never heard it until the TV show. – Loren Pechtel Jun 26 '17 at 04:07

Maybe this is a Midwestern thing, but I'd say something like, "He used to be a good cop, but now he's gone crooked, mingles with the gangsta on the street, sad thing."

A bit like "broke bad," but I'm guessing crooked is understood more widely.

Perhaps your guy has fallen as in a fallen angel.

He "fell" implies one was on a good path, yet not only has stumbled, but is down (bad) and no longer upright.

    I think fall has too many meanings for it to be properly construed in this context, absent a qualifier. "He used to be a good cop but he fell," to me, makes it sounds like he was killed. – AffableAmbler Jun 20 '17 at 16:57
  • 2
    @Noah True. As OP asked for a verb, "fall" with context does work well with "'fall from grace", "fall off the bandwagon", "fallen angel", Like other answers, break, go, move, something more than just a verb is needed. – chux - Reinstate Monica Jun 20 '17 at 17:29

    I'd suggest you say that he's fallen rather than fell / fall – RemarkLima Jun 22 '17 at 06:23

Consider strayed which, in the context, implies good guy becoming a bad guy.

He used to be a good cop, but now he strayed and mingles with the gangsta on the street, sad thing.

Collins:

stray verb (intransitive)

4. to deviate from certain moral standards

Collins English Dictionary. Copyright © HarperCollins Publishers

Parents feel distressed by children who have strayed.

    From all the answers in here, this seems the most appropriate one, since straying actually implies a literal deviation from a "good path", while turning can be used in both "ways" and may imply that there was a specific trigger, as Charles suggested in a comment. – Armfoot Jun 22 '17 at 18:35
  • 1
    To me stray has a temporary feel. As in, he strayed but got back on track, for example in a marriage. As opposed to fallen, which is not sideways and reversible but downward and virtually irreversible, like with a fallen angel. Actually, the example with the children illustrates the point pretty nicely. – Peter - Reinstate Monica Jun 26 '17 at 12:28

    @PeterA.Schneider, it is possible to stray and be lost permanently as much as it is possible to fall and get up. – alwayslearning Jun 26 '17 at 15:01

"Degenerate" seems the best single, non-colloquial word.

X wrote an interesting first novel, but he has degenerated since then.

The word has a different meaning when used as a verb than when used as an adjective or substantive.

He defected.

Merriam Webster:

  1. To forsake one cause, party, or nation for another often because of a change in ideology
  2. To leave one situation (such as a job) often to go over to a rival

EDIT: I should add that your word choice depends on the tone of the writing. If it's modern or casual, turned works well. If it's more formal, defected would fit better.

    Defection would imply a change of faction, so in the example, if the good cop quit and became a gangsta then "defected" would fit. However, if he remained a cop but was simply no longer good, I'm not sure that "defected" would really apply. – Steve Bird Jun 22 '17 at 14:40
  • Defected works both ways. He was in the mafia but deflected and now works as an informant for the cops. – Pieter B Jun 24 '17 at 11:54

    Not sure if this is right - in my understanding a good person being debased remains good but kind of tainted or hurt. Not the meaning OP was asking for. Sorry, I think I must downvote. – Felix Goldberg Jun 22 '17 at 08:23
  • 1
    @FelixGoldberg - "remains good" is in the eye of the beholder after someone's character deteriorates or lowers in quality to a point which implies a loss of position, worth, value, or dignity, or having (what, in the eye of the beholder, is) corrupt or impure virtue. – Mazura Jun 22 '17 at 13:44

If the cop turned due to too much hanging out with thugs, you could say he's gone native.

adopt the lifestyle or outlook of local inhabitants, especially when dwelling in a colonial region; to become less refined under the influence of a less cultured, more primitive, or simpler social environment.

Dependent on context, you could go with something like succumb

fail to resist pressure, temptation, or some other negative force.

Though I guess you'd like something more idiomatic.

There is a phrase to describe this event in American professional wrestling: The heel turn. It's still possibly too esoteric for your needs, but it's definitely not got a law enforcement origin.

If the person was previously a bad guy, then became good, and is now becoming bad again, you could say he's regressed. (Though this is sometimes a psychiatry term too.)

He used to be a good cop, but now he degenerated, mingles with the gangsta on the street, sad thing.

If he had been bad and then turned bad after being good for a while one could say he "backslid" or 'relapsed".
