Regret

Is having regrets necessarily a bad thing? It seems to have become a "fad" among young people especially to claim that they have no regrets, or that life is too short to regret anything that you do, because, after all, it was what you wanted at one time. But is it actually even possible to live life and not regret something? Why does "regret" have such a bad connotation? In reality, we all make mistakes, and we all have done things that we wish we could take back or that we would do differently if given the chance to go back. Do we see regret as a sign of weakness? This is not to say that we should live in the past, but we should be able to admit our mistakes, even if only to ourselves. It's OK to have regrets. It's part of what makes us human. If we really had no regrets, then what kind of people would we be? Either we would have to be perfect, which none of us are, OR we would have to be inherently bad people. If you do bad things and you don't regret doing them, doesn't that make you a bad person? So, it follows naturally that a "good" person must have regrets, since no one is perfect.
