Smile Vengeance

At times, It's quite amusing
Watching as you squirm.
Taking in my happiness
Which makes your iced blood burn.

You know? It may be cruel of me,
But I can't help but smile
Every time I see your pain,
Brutality is worth while.

I suppose it's due to how
Deceitful you have been.
The cold blades you've plunged
In my back are fuel for all my sins.
