I don't think they should blame the games for these crimes at all! Clearly there is something mentally wrong with these kids, I don't mean in a bad way, just that simply if you are desperate enough to kill someone you love over a disagreement, its just sad
I do think the one about the Romanian boy had something to do with him being adopted though... well, in the way that the people weren't his real parents, so he may not have had a very close relationship with them someone who had been born to their parents... but then it goes on in the one about Daniel Petric and says he was a Momma's boy, and ironically she was the one he killed.
Idk, I prolly shouldn't be looking at this so psychologically, but it just does not make sense to say that a game in itself caused a person who can think for themselves to commit such acts of horror
