You get rude on small things, when someone kills you for much time you get angry and start being rude to him.
Even when you rule break and someone teaches you the rule, you still get angry.. The thing is VU doesn't promote a member until he changes. You were same (before and after in UF), what if you never change yourself and VU doesn't promote you. Will you leave the clan too as for you think yourself changed but actually is not?
