Thank you all, very much. It seems the problem of good vs. bad is quite strong among Asperger people, or it can be conscious vs. unconscious, I don't know.
You know, the thing is, I know several people with Aspeger outside of the family, and they never stand on the opinion of an absolute, natural and unchangeable rightness of them in every situation, as weel as they are not so often totally furious as he is. In fact I have almost the opposite experience with them all, same as me, that there is an apparent ability of gaining SOMETHING from any new experience (which is every dialogue and every encounter with another person), despite the fact the process of GAINING the experience is not easy. In practice, when somebody is not OK with me because of my unsocial or unusual behavior in a particular situation, it is not problem for me to analyze the situation, especially after some years, I am familiar with them and I am able to APOLOGIZE or at least to consider clearly, that there was something in MY behavior leading to the unpleasant reaction of surrounding people. Yes of course it does not necessary mean I am always able to CHANGE it, or change it IMMEDIATELY, but I made a big progress even in it, just with regards to the EXPERIENCE and my age. After years, I see it much quicker, so my reaction is faster then any before and very often so fast than it precludes the problem to happen.
He is quite old and he is not, or he pretends he is not, which I am almost convinced is the case, and that's why I consider it as conscious and manipulative, and it literally confuses me. He had experienced many situations when people were totally caught off-guard by him, and he is not mostly regarded as the pleasant person, among people who know him for some time already. He is usually very charming for people, especially women, at the first sight, because he is talkative (really too much!

), but after the second or third longer conversation (let's say monologue more precisely), full of lies what he knows and where he was (still interesting for them) they fall into doubts and then usually some conflict appears quite quickly, when he attacks something the person likes to do etc. There is no any sign of the good will or something like being aware of his own problem, even I can't absolutely tell he is the EVIL person, it is not so simple, but he is - literally, in his opinion and his view of the world - the only person in the world who is right in everything, the only important person in the world, he as the only one knows everything the best - so logically, there could'nt be any better way than the best which is his. And with combination with his lying, it creates terrible hybrid situations.
Yes, you're perhaps right, the more I write about him here and now it seems, it will be probably "only" Asperger, but let's say the really dark side of it, although I am still confused I haven't observed it so much in other Asperger people... He does not do anything deviant in the proper sense, if for example the violence on the pregnant woman is not regarded as deviant, which I don't think so, in the proper sense, it is brutal of course, but I would no say "deviant" like with sexual or similar subtext, neither he does have any really strange habits like in Silence of the lambs

or tearing away the legs of insect and so on

Yes, perhaps it could be the difference, because this is perhaps the behavior specific for sociopaths and necessary for their diagnosis. But still it seems to me, there is too much "conscious "evil" ", to my opinion, possibly an egoism tax.
