Fangs and claws

Fangs red with blood
Claws painted crimson
My enemies are all dead
I've devoured them all
I killed their families just for fun
I no longer feel the remorse
They've hurt me so I've hurt them
Equivalent exchange ain't it sweet
Eye for an eye blood for blood
Next is the world
They've shunned me
And sent me to that horrible place
I will kill them
My claws my weapon
My resolve never wavering
They will all feel my pain
I'll burn hospitals and schools
Devour the young and the old
Nothing can stop me
No one will try
