It's not an original idea at all, but I think it's pretty okay. What do you think?

PARASITE

I am the mind cusher
I am the dream smasher
All the hate inside you
I am the mask that hides you from yourself

When I murder, it's your head they hunt
Blame is on yuo for my every stunt
You try to run, but I rise everyday, like the sun
You cannot escape this parasite
Your soul is my paradise

I am the death dealer
I am the bone breaker
All the hate inside you
I am the mask that hides you from yourself

You will become worthless one day
When I've recieved my just pay
Had my fun, you'll just be left with this pain
When you've lost this parasite
You become a soulless crash-site
