People playing online in a game where they are supposed to compete against each other can sometimes lose themselves, both as players and as characters. Unfortunately there is no cure for being a jerk, although it befalls the leaders of the realm to make sure such nobles who are unable to follow proper decorum as expected of any noble do not get anything like lordships, council positions, marshal appointments, etc.
Basically, if you couldn't talk like a noble, act like a noble, have the proper decorum and protocol to act completely in control of yourself even if you were inwardly fuming, you didn't deserve to lead anyone else, nor deserve to be a model for the lesser nobility. I believe the saying goes something like "He who cannot control himself is unfit to control others"?
