Reverend Bizarre demons annoying me

Crawling from the dark
Calling me with names
The evil-ones from past
Tormenting me, until I'm insane
Straight from the depths of hell
The demons come to me
Every night and day
The demons in my mind
They won't let me be
Once I had been knows as a man with a pure heart
But suddenly something changed
I felt like my soul had been torn apart
The evil deed of mine can never be washed away
I killed the one I loved
And now the demons come every night and day
