It's someone who tends to be a nice person but hides something or there is something off about him. Sometimes, you meet this kind of people and you know that his/her kindness hides a darker side.
I thought about sly or shady but they seem a bit too much, however I might be wrong. Is deceitful the correct term or is there a more specific one?
Example :
"I don't like the new boss, his kindness hides something"
" I don't like the new boss, he is _____"
As an adjective, I would like to use
hypocrite
hypocritical
insincere
double
double-faced
two-faced
double-tongued
On the other hand, as a noun , I would use
dissembler
prig
pharisee
double-dealer
How about "two-faced"?
two-faced is an adjective you can use to someone who acts one way at a certain time/situation but acts differently at another time/situation.
Sometimes, the answer is right under our noses. At least in my case, I would refer to this person as fake.
It requires some understanding of connotation, but in this case it lends itself quite easily:
"I don't like the new boss, his kindness hides something. Does he not seem fake to you?"
The first word that I thought of was smarmy:
Also obsequious, although this implies that the speaker is a sycophant:
"Dissembler" might fit your requirement. Though you might have to tweak the sentence a bit. "I don't like the new boss, he seems to be a dissembler." This is because "seems to be" adds the connotations of having picked up such vibes from the person. "Is" implies more of a certain pronouncement on the character of the person.
The entire thinking error goes kinda like this..."hides behind acts of kindness to commit atrocities." Now this is not exactly the way I saw it written which is why I'm asking.
When the thing the person is hiding is an intent to do you harm, we have the specific phrase:
wolf in sheep's clothing.
