Becoming Darkened

On the outside of the wall
Nothings really there
On the inside of the wall
No one will ever know of
Darkened souls you'll always fine
But kind ones are extremely rare
And like the blade they all stain
It'll stab your heart
And you'll bleed horribly, forever, and eternally
May you die and suffer through horrid things
Unspeakable in human terms
The heart shrivels up
And twists and breaks
Your becoming darkened
And dying inside
Dead forever after
