To me, not necessarily, but it is a kind of obligation that parents and guardians occasionally worry about over their children--a positive or negative effect on their children.
Most parents wouldn't like to have their children take a drug-addict or alcoholic for their idol. Famous people are well-known, and are constantly being watched of their actions and behavior. To the public, a most obvious "obligation" is being a role-model: Having a squeaky clean image and record. They don't want Lindsay Lohan to affect their fan's actions--like getting D.you.I.s or partying when not supposed to be. Or Kristen Stewart--being a famous child star being caught of doing pot.
But that is only one of the "responsibilities" famous people are expected of by the public.
