"Mercy" lyrics

I went thru too many people
I went thru heaven and hell
I went from rome to bagdad
Too many stories to tell

I lived thru too many aeons
I've risen up and I fell the fall
I have been there and I have done that
I've seen it all and all

My time is running like water
Deeper I dive and deeper
Last of nine lives of the cat
I saved my soul for the reaper

What do you mean by that
Mercy is all you get
Do what you won't regret
Freedom's your self-respect
