Snape vs. snape

There was a time when you could not trust me
and there was a time when darkness was all I could see
but now there are no layers of evil left to shed
and if he heard me sing this song I would be good as dead
people can change, people can change
they can turn their back and run
people can change, people can change
I'm sorry for all the things I've done

People don't change, people don't change
once a Death Eater, you're always one

People can change, people can change
they can turn their back and run
People don't change, people don't change
stop running, it's you you're running from
It's you you're running from

Now the dark mark it has appeared on me
Lord Voldemort, he calls
but I want to be free
from all the evil I have seen and I have done
So please believe it's over
the good in me has won

I won't change, I'll never change
Lord Voldemort has won
Lord Voldemort, he calls
