Separation of Powers, good question, and yes, everyone is different.
Do you think that you have a good enough relationship with family that you could lead the rest of the family away by example? If you just stopped, would they think, hey what made brother quit, something must be wrong with the org. or he is upset with something?
It is possible that some in the family are continuing for the reasons you stated. I don't know if you are in the same hall or not, but if one sibling might not want to stand out from another with mom or dad. But I don't know your situation.
