I've said this before on the forums. But I have great difficulty feeling empathy with anyone who is permanently banned. You're warned three times with ever-increasing punishments before you are removed and cannot play again (usually, that is.) And it's not like you are not given a chance in between. If you go several months without being punished, you won't automatically get the next step up. Riot seems flexible on things like that.
But more "fuel on the fire" is many people who post their chat logs do not seem to comprehend that they did anything wrong. "I called the guy a ^blank.^ So, what?" People point out to the player the error. They still don't get it. Odds are that these are the folks who will make another account, get punished again, and STILL not understand why. I don't have the patience to deal with people like that. One person I know used to say that I "did not suffer fools." Well, okay. One statement seems a bit harsher than the others.
I'm not going to sugar coat it for anyone. I am just not wired that way. If people don't want my opinion, I won't give it to them. But it's a little difficult to do that by posting on a public forum and then being angry that I responded. Now, all that being said, I'm not going to cuss you out, be insulting, or break forum rules posting responses to these people. But you're already condemned. You can't, and shouldn't, expect much from anyone else unless you sincerely regret your actions and really want to change. And that just isn't the norm for people who are banned.
