Another school shooting

[Guilmon and a shotgun]

Yes, access to guns was a problem, but it would be great if we knew what it is about society that causes people to do these sorts of things.

It's always emotions i think, society would just an environmental factor to spur them on. If it's not for revenge, it's for fun/envy and even the popular "You're a little bit different to us, we're allowed to hate you for it" mentality as i like to call it.
If the imagination of a human being can go to extreme levels, it can take hold of these emotions and can lead the person to believe it's real, a will of religious nature or "right"; this in turn leads to the killing. We've seen it in religion, antisemitism and even schizophrenics.
In fact, imagination at these levels may just be a trait of evolution; anomalous brain development might just be defected evolutions that have no place in a modern society. So what do we do with the people who have these evolutions? we put them all together in cages because we morally object to shooting them.

That's my theory anyway, you can all just say it's the fault of society if you like.
