[Avatar TLA/LOK] What would happen if an avatar refused to be the avatar?

I mean think about it. No one chooses to be the avatar, they get chosen. With that comes all the power but also the responsibility of pretty much solving the worlds problems. What if an avatar didn't want to do that? What if they wanted a simple quiet life or something?

I guess there could be spiritual problems caused by the previous Avatars being  upset but rejecting them hard enough seems to weaken the connection between the current Avatar and the previous ones to prevent forced communication. (That's what happened to Aang after the events of the first series because of a conflict with Roku until their reconciliation, even if maybe not all Avatars could do the same thing because they don't all have Aang's spiritual control)

One of the Water Nation-born previous Avatars was a laidback surfer and basically did nothing so he was unable to save his fiancee. (but otherwise he was an avatar born in a generation without great conflicts)
