Human aggression is instinctual. Humans have not evolved any ritualized aggression-inhibiting mechanisms to ensure the survival of the species. For this reason man in considered a very dangerous animal.
-Konrad Lorenz-

It's just instinct.
That's all it is.
I understand now.
That you've let go of all your progress
and just let yourself go back to the level of humanity
that lashes out and abuses
because that's what the little voice
in the back of their mind
says to do.
Well you know what?
I think I'll listen to the little voice
in the back of my mind
and tell you what it wants me to say:

Fuck you.
