We have all sinned, every one of us. Even if we didn't realize it at the time, we see our actions years later and are disgusted with ourselves.
The time for purity tests are over, it's time to admit that deep down the human experience is being a giant piece of shit, but it is also trying to cleanse yourself of such burdensome humanity and grow into something far kinder, far smarter, far more empathetic, far more patient, and above all, far more wonderful than a human being.
