Lifeless?

First poem I ever wrote. Originally written for school.

Drooling over himself,
Like an infant;
Moaning over pain,
Nonexistent.

Stumbling over his feet,
Without direction;
Body rotting away,
Filled with infection.

Chasing down his prey,
Like a savage;
Followed by his kin,
Ready to ravage.

Biting through his catch,
While the others smother;
The victim rises again,
Their new brother.
