Devil Incarnated

Everyone has a devil
Deep inside but they dont know
Animal cant kill human
But human can kill everything
Slam the head to prove a war
Stab forward, dont say a word
Money first, the rule that old
Work till death, to find power
Dont you see the air around of you covered by
Blood and hate, it will never change untill you are all dead
Kill to eat, just to exist
Kill for fun, just to show off
Kill untill turn to a beast
We are all beast but we denied.
