I would actually like to discredit the title of this thread...
I do not, for a second, believe that the female from the article posted by the OP is crazy. I would actually argue that she is completely sane and is just a vindictive *****.
It can hardly have escaped most people's attention that quite a large number of individuals within the human race are selfish, arrogant, uncaring idiots. I personally think that this woman knew exactly what she was doing and probably justified it to herself with the though of "well I got hurt so why not hurt those ******** back!"
I do however find her actions to be completely deplorable and think that the punishment does not in any way fit the crime. However in this day and age with the threat of STDs, forced paternity/maternity support then the men involved were complete idiots.
