Everyone deserves another chance, regardless of what number chance it is. As long as he is actually sorry for what he did and wants to change, he should get another chance. It doesn't matter what he did. If he messed up again then punish him again, and if in the future he is sorry give him another chance again.
You may not know if he's actually sorry and will change but you should still give him the chance. Don't act like you all have never needed another chance before.
It's nice to have the mindset that we should constantly give one-another chances to be forgiven but sadly, it defeats the purpose of a permanent ban. Not to mention the fact that the amount of times they've been given 'another chance' is entirely relevant, if they have consistently broken rules after being forgiven then Loka should move on instead of discussing if toxic players should be unbanned.
This isn't personally direted at Nova but I find the idea of unlimited chances kind of ridiculous. If this was the case there's really no sense in perma bans at all, instead it should just be lengthy temp bans. An example of why chances aren't handed out with ease is mossebobby.
I'm not really fimilar with Nova's entire history of breaking rules so it'd be unwise to make an opinion without all the facts imo.
