Forgiveness is generally for the person who has been wronged, not for the one who metes out punishment. You can "forgive" someone who's harassed you all you like, but you're for some reason confusing the punishment with some sort of personal catharsis. The punishment for doing horrible things is not mitigated by the people who were wronged feeling forgiveness. If you murder someone, in some states where I live you get killed right back. Forgive it all you like but you are dead and that cannot be taken back.
Your view on this is incredibly naive. A police officer working on this principle would be just as likely to waive your parking ticket as you stabbing someone. "oh well, you only did it once, go ahead and take this warning". Severity of punishments being relative to the infractions is how many MANY systems of law work.
You confuse this falling off the record as some sort of after process that should be set on every single judgement when it's very clear that if someone does something that's clearly more harmful to everyone elses gaming experience they should be punished accordingly and that punishment should include never having that infraction falling off their record.
Even if we speak of merely personal affronts , constantly forgiving someone for say lying to you or cheating ON you just as easily as say forgiving someone for stepping on your toe accidentally is just .. well.. asking to be taken advantage of.
Then don't consider it "forgiveness" but the price of the action. The punishment as it were.
I'm always aghast at what people can possibly defend here.. but you've very much awestruck me with how nonsensical someones stances can be when they don't have to answer for anything they say.
