Exactly! That is what I was trying to say that he is mentally unsound. Not stable.
Lets say for example that a girl did tease him a bit in a bar or nightclub. Just a bit not too much or in most cases girls don't even talk to their rapists. The guy is mentally unstable and a big pervert. **Gets the date rape drug and drugs her drink or whatever and makes her come with her to some other place. **He rapes her and she has no memory of the incident. Her fault? Nope.
Why did she take a drink from an un known man?
Why did she go to some place with an unknown man?
