If he had been willing to do that, he wouldn’t have received “do not mess with time”.
Though I notice I’m confused as to how, exactly, the universe can figure out he’d create a paradox in this situation without actually running the computation to see what happens. Probably it can’t. Probably time-travel is hilariously unethical.
The universe isn’t limited to object-level proofs that exist in the universe, I guess. Perhaps the universe has access to the list of everything which is true about the universe?
I don’t. It’s not accessible from the object level, or any combination of first-order meta levels. it takes at least a second-order meta (2°meta:1°meta::1°meta:object) to create such a list, and I can’t even begin to explain what second-order meta means.
Well, I can consider the analogous situation where time travel is repeated in an attempt for Emperor Yingling of Scandinavia to convince all of his respective kingdoms to adopt ultimogeniture secession before he dies, so that his youngest son won’t have to fight secession wars as he tries to expand into Rus while defending Aragorn from upstarts who object to imperial expansion by marriage.
I don’t think that save-scumming is immoral because simulations are dying, although I am receptive to arguments that it is immoral because it breaks the rules.
Given that this universe settled on an explicit message about not messing with time, and given how much magic apparently involves naive mental entities, it seems like anthropomorphizing the laws of physics is a much more useful heuristic in the HP universe than it is in ours.
I was thinking about how I’d implement HPMoR-style time-travel in a turing machine, actually.
It goes something like this:
Compute every possible future that doesn’t contradict something in the fixed past, including loops.
Whenever you find a paradox, delete that timeline.
Repeat.
That would generate a story we could read, no problem. It wouldn’t generate anyone who actually experiences paradoxes, either; to the degree those actually exist, they never get out of the subatomic level. It’s not clear to me whether or not this results in a universe that can usefully be experienced, though, or (more to the point) whether your future experiences match up with the type of experiences you remember.

Well, how do you make that list?
I don’t. It’s not accessible from the object level, or any combination of first-order meta levels. it takes at least a second-order meta (2°meta:1°meta::1°meta:object) to create such a list, and I can’t even begin to explain what second-order meta means.
All right, so long as you realize that means you can’t evaluate whether or not such a thing is possible. :-)
Argument from confusion doesn’t work.

I think you’re inappropriately anthropomorphizing the universe.

..kind of odd.
