I wish I could say you were doing quite well, but it's clear to me that at some point during our travels, you've gone a bit awry. History, being one of my personal best subjects, is something you appear to be lacking in. You've bounded about the universe so often you've forgotten exactly why we follow the rules that we do, haven't you? That business on Mars, that poor woman. Perhaps the concept of consequences has long since abandoned my senses, though I never did expect myself to go so utterly senile.
So, since clearly you're confused, let me sort you out:
Stop it. Stop this and stop it now. Look at the timelines. Look at your life. Think about the things that you're doing! Think about the things you're destroying through your cruelty and carelessness! We're better than that, aren't we?
What you're doing is wrong, and you know it. Leave history alone, my boy, leave time alone, and do what's right. I don't care how long you've been exiled or what sort of a god you think you are, but you mustn't touch history.
Not one line.
