We have this expression in Hindi slang. Situation:
A: "I can't believe he treated me like that. I was stupid to trust him"
B: "Don't beat yourself up. How were you supposed to know he would stoop so low? After all, a**holes don't walk around with horns on their
heads"
What B is trying to say is that bad people don't have distinctive physical characteristics. They look like normal people and there's no way to tell them apart.
Is there some English expression that conveys this?
