Severus Snape

Severus Snape, you are the Half-blood Prince,
but there is no escape
from the Unbreakable Vow.

Severus Snape, you excel in potions
with the notion
to poison your students especially Harry Potter.

Severus Snape, you are Death Eater,
but you say that you are reformed from evil ways.
You got everyone fooled
in your guise.

Severus Snape, the Dark Arts fascinate you,
so you invented several jinxes and hexes.
You got no escape for you for what you did.

Severus Snape, you murdered Dumbledore
because of the Unbreakable Vow.
Now you got to pay for your crimes.
