Dangerously fragile

My heart a fragile thing
Bearing chaos can cause it to break
Once broken, you can't find all the pieces
And it remembers all the reasons.
The reasons why it got damaged
And honey, you did to your self all that damage
My heart is immortal yet you're not
And I know how to mix up a poison to tear you apart
Your face turns green and your limbs twist
And that's when my fun and joy begins.

My heart breathes and it feels.
Your vicious deeds,
it sees;
While your righteous deeds disappear.
You'd be nothing but a powerless demon to me
And me an angel that would purge you entirely

My heart is fragile but not like a flower pot
But deadly and dangerous just like a destructive bomb
