For sure, a lot of these mob guys are probably very charming or funny or dare I say it likeable. That's the sad thing about the human race and the ability to manipulate. Some people will invariably use gifts they possess to part fools with their money or take advantage of vulnerable people.

It's said that a lot of psychopaths are CEO's of big companies.
