It's irrational to assume you can ever truly evaluate yourself as a good or bad human being. You will never have enough information.That "bad person" at work who torments you might be an excellent father to his kids. That other "bad person" at work who screwed up royally today? That error might later lead to a huge breakthrough. We will never have enough info to holistically evaluate a person and score them in totality as "bad" or "good."

Guilt is not the best way to remedy your mistakes.

What sentence will you choose to impose on yourself? Are you willing to stop suffering and making yourself miserable when your sentence has expired? This would at least be a responsible way to punish yourself because it would be time-limited.

Kindness is the cause of all anxiety.

The best way to confront your fears it to stop avoiding the situation you're most afraid of.

Forgiving yourself, not guilt, increases personal accountability.

When we're rational about rule-breaking we set a limit. You don't get 30 years in prison for a traffic ticket. But sometimes you sentence yourself to months or years of emotional pain over minor offenses.
