Realistically speaking, who in their right mind would want to be the king of Olympus? Having to manage all of the violent and idiotic gods like some childcare worker seems like a nightmare. If you really think about it the hades has it better than all of the other gods. Unlike Zeus and Poseidon whose realms are somewhat close to one another Hades has the afterlife which even the gods can't easily enter and exit as they please. He also holds a position in Olympus and can go there if he really wishes to do so. Anybody slightly familiar with the mythology knows Hades was never banished or banned from entering Olympus but he just never felt it necessary to go up there. People always confuse Disney's Hercules story with actual mythology. Even the Riordan's version of him only being allowed on inside in the winter solstice is a bit wrong as there are many myths of him randomly popping up in Olympus for whatever reason he deemed fit.
