What would it have mattered?

Im glad i hurt her.
I'd hurt her again.
I wouldn't change a thing.
She tried to hurt me so I enjoyed every tear she cried over me.
I guess that kinda makes me a bad guy.
But I don't regret being that way towards her.
She didn't deserve to see me at my best.
So I made her watch me at my worse.
What would it have mattered if I cared?
I wouldn't of been a better person.
What difference would it have made if I was honest.
What would have sorry mattered if I actually meant it?
