They're probably just people trolling to get a reaction which is still just as bad when it concerns a situation like this. I wouldn't be surprised if there were guys who actually defend him though because they've probably went through a similar situation. This causes them to sympathize with the killer in this situation... anyways this whole thing is just wrong. He took innocent lives of people who had nothing to do with his situation just because a girl rejected him. A girl definitely shouldn't have to force herself to be with someone just like that. At best she can try and get to know him more (assuming she doesn't) and make her choice. I'm pretty sure a guy would do the same if a girl came at him like that when he doesn't share the same feelings.
