Should I feel bad for a moderator that banned me?
Why would you feel bad for him?
He's clearly in over his head.
It's good that you have pity for someone who is struggling.  Maybe in the future, that pity can lead you to not doing the kinds of things that got you banned in the first place.  That'll make it easier for him, right?
Who said I was sad about my ban? I'm genuinely happy he's having a hard time. If he doesn't get his act together, I'll go back just to troll and spam.
That seems very inconsiderate and rude. You need to start   treating people better and being nicer to others.
