Genetically predisposed
Proclivity to violence
Motivated by desire
Hunting the land in silence
Picking the flesh from the bone
Greedily devoured
Prey on the lives of all
The apex predator

Devour them limb from limb
Beaten, trampled and mauled
Aggression is an instinct
A savage neanderthal
Primitive social system
Divulge Cro-Magnon traits
To masticate, mutilate
Procreate and defecate
