I don't trust life, anymore
I don't want to see humanity, anymore
I don't want to hear their fucking voices, anymore
For who they are
And what they are
This means war

And punish
And crush
The world is my enemy

Break apart
Slash and burn
This world is my enemy

I don't trust society, anymore
I don't even trust my own friends, anymore
I don't want to see their fucking faces, anymore
For how it is
And what it is now
I shall declare a war

Against humanity
Against myself

Destruction is all I want
Pain and suffering is all I want
I want all my fears gone
I want all of you dead

Can refer to some criminals that had a right disdain for humanity (and I think the Virginia Tech shooter was one of them).

To be honest, I felt like this a couple of years ago...
