Paint the wall with my brains

Today, I hate humanity.
I want no one to escape my rage. If I could shoot every single persons brains out, believe me I would.
I'm like that, I might shake your hand, I might blow your head of with my own automatic weapon. You never know.

Or someone could you just be so kind and put a gun to my head, and paint the walls with my brains.
I am going to dye somday, why not today?
Why not today?

Tomorrow I just might shoot my own head of, or step in front of a bus. You never know.
