ghetis in pokemon black2 since all my pokemon were underleveled by at least 10 lvls from critting too many battles and not evolving most of them til the last gym rip
if you can do it to save a friend's life, sure let's go back in time to do so please
otherwise I can't think of anything death is already scary enough I rather not plan it out theoretically
I usually try to solve it immediately so my conscience is in a good state before I let it weigh too hard on me! If I'm not comfortable with the situation though, I take my time with it until I can face it head on
