Except then you'll always beat up on the bad decisions. Ponies are thinking they'd do better than the princesses because they don't know the full situation. They're even ignoring the facts that are right there in the open, because they're angry, and hurt, and don't understand.

So they'll always use it as justification for "I can do better than THAT", and that makes them resent whoever made the mistake.

That's not really any good, either.
