The Evil Mask

I wear a mask
That hides my true self,
That hides all the lies,
That hides all the kills.
I wear a mask
That makes me look nice,
That hides the evil monster that lives inside me,
The mask stops the demons
That want to escape,
That want to go kill,
That want to oppress.
I am the villain and
What are you gonna do?
You won't do nothing because I scare you!
