What exactly were you trying to prove?
I found this flash to be pretty meaningless. There are countless flash movies on NG about killing people of all race/cultures/creeds which no one has a problem with, but when it comes to a flash movie made by an individual who did similar actions in real life, everyone jumps all over it saying how it obviously shows how deranged the person was. Anyway, my problem with this flash is it seems like you are trying to somehow "get back" at the original author (Who is now dead by the way, so your apparent criticism of his actions are meaningless and will go unheard by him)
I really don't think this deserves front page and I don't see where the spectacular message is that everyone claims it gives. As I said above, NG is full of countless VERY violent animations, many of which are way worse than this. So if you're picking on the animation for being violent, then you obviously are completely blind to everything else on the site, and if you're picking on the creator for his actions done in real life, then you fail because he is dead.
