Chronic Hero Syndrome is an "affliction" of particularly idealistic protagonists which renders them unable to say "It's Somebody Else's Problem". Every wrong within earshot must be righted, and everyone in need must be helped, preferably by Our Hero him- or herself. This is extremely common in video games as a way to make the player deal with unimportant plot threads like Fetch Quests when they should have more important things on their minds. The characters are just too darn heroic to leave people to suffer, though, so time to go wander around in caves for a while.
