A Bad Process Can Produce a Good Outcome — That Doesn't Make It a Good Process

This is called resulting: judging the quality of a decision by its outcome rather than by the process behind it. A drunk driver can arrive home safely — that doesn't make drunk driving wise. When something works out despite a sloppy approach, we're tempted to think the approach was fine. But good outcomes from bad processes are just luck, and luck runs out. Evaluate your decisions by the information and reasoning you used at the time, not by what happened after.
