I've known several people with Asperger's/autism and some have a problematic lack of emotional maturity, worse than the average person. I also know awesome people with AS who definitely stand out in a positive way.
I kind of recognise it, yes, but I wouldn't say that they're more 'evil', just sometimes so immature it causes them to behave in childish, pathetic or downright terrible ways. Also, lack of ToM can make their behaviour seem a certain way without the appearance matching the intent.
And this same lack of social understanding can make them hateful and resentful because they continually misinterpret other people's behaviour, usually in a negative way. (or it turns negative after they get in some kind of -social- trouble because of all the miscommunication, leaving them disappointed etc) This can lead to uncharming habits.
But it's not like they're 'evil'. Their behaviour however can be more ugly than usual due to the complexity of some people's problems.
