Hey, if it ain't broke, don't fix it. Earth was a mess back home the last time I visited it. All this infighting and everything, and then an alien invasion that they weren't prepared for because of the infighting. I decided I was better off doing stuff in space because at least I knew what I was doing, and at least up there everyone fights the bad guys instead of each other.

Nothing wrong with staying in your lane. If it turns out this universe is more your lane...
