Past you made those choices with less information than you have now. Judge the decision, not the person.

Judging an old decision with what you know now is not a fair comparison, because past you had a fraction of the facts and none of the outcome. The choice can still have been the wrong one. The person making it was doing their best guess in the dark, which is the only condition any decision has ever been made in.

Separate those two things next time you replay something. Ask what you would have needed to know, and whether you could have known it. Take the lesson and leave the verdict.
