I guess observation bias suggests that you're right. But there's a part of me that hopes he saw everything. At the time, I made a choice based on the idea that he was right about there being only one way to do something. Or else, the idea that it was inevitable gave me solace about the choice I was going to make anyway. I now realize wasn't entirely true - there wasn't only one way - but the other way wasn't any better. I just doomed someone I cared about to my own ultimate fate.
And obviously, I know there are a billion more universes where I never had to worry about this at all. And a billion more where I don't exist, and never did, and never will. And probably at least a trillion where humans never managed to emerge from the primordial soup. Which, good for them, honestly. We're always on the brink of some ridiculous disaster. Maybe it's nice to just be soup.
But to your point, yeah. Kind of an arrogant prick. You don't call yourself the Sorcerer Supreme because you've learned to keep your ego in check.
