It's impossible for anyone to meet the expectation of being the savior of the world.
I could forgive my own brother of anything, at the end of the day, because we're brothers. You can't get in between that blood. 
I find it valuable to watch what I do. I like to know when I'm making a choice if it actually works or not.
Forgiveness is a sacrifice. You're giving up being right about something, whether you're right or wrong about it.
