But Duanmu Huai is unwilling to do such a thing, for one, he is naturally impatient and can't handle the kind of waiting game like this. He can't even fish patiently; if the fish didn't bite, he'd just throw in a thermite bomb. Having Duanmu Huai do something like this is no different from being in prison as far as he's concerned.
Plus, Duanmu Huai knows the corrective nature of history, so what if he stays here? Who knows, maybe he has to go to another planet to use the bathroom or something, and when he gets back, Cadia's already blown up. Wouldn't that be a waste of time?
Duanmu Huai already has enough trouble dealing with the Evil God, he doesn't want to also face the corrective force of time, that would just be looking for trouble.
Besides, Duanmu Huai feels that he has already done enough this time.
