Alimentive Distraught

To whom do I owe this distain,
for mine torments tumultuous rain?

Internally corrosive leach of Sin
I am, and thus, forever have been.

Doomed to drown, distraught desire.
What hights doth Alimentiveness aspire?

Temperance chains rust and wither.
Into mine gullet, I bid you, slither.

Decomposition's archaic rune,
for even vengeance, I consume.
