Good flash, bad choice.
the animation is really good and fluent. Great sounds, although a bit too loud. It was short, and was missing in the humor section, otherwise this is great.
There, I rated this flash without taking points of for his acts of violence in real life. To everyone that may read this, though, DON'T do the things he did. It's selfish. Everyone has a period in life where they don't see the point in living, and yes, some never get over it and decide to kill themselves. And yes, maybe the teachers and some of the students at his school were total assholes and deserved to be shot.
But no, there's no way everyone else deserved what he did. These kids have parents, these teachers have wives/husbands. These people have other people that know them, perhaps respect and love them, and he takes them away. Bottom line: If your life sucks, okay, go ahead and kill yourself. That's your choice. But don't drag people down with you.
Considering I don't know all the details about this, I'm just going to be positive here and assume he had a reason to do this. And in that case, I blame society. These things happen more and more nowadays. Why? Because the people who do it are retards? Because there are more of those kind of retards nowadays? No. Because society is fucking up. There's too much people with too much greed. Let this be lesson and an eye-opener to people. But in no way think that it was a good idea of this guy to take others down with him.
