That doesn't help you, does it? It's like saying there are so many unsolved murders, why does the police bother arresting me? Or, why do I have to get a speeding ticket when so many other individuals drive way too fast as well?

As decodx rightly pointed out, can you name a few reasons what Bitcointalk would lose with you gone? To put it differently, can you list what Bitcointalk gains if the admins forgave your violations and unbanned your account/accounts? Those are some of the things the admins will look at. Community support is also important, which is something that is not easy to get as you can see.
