Everybody wants a benevolent dictator to take care of things for them until they are victims of power abuse for an edge case they didn't predict yet was inevitable.
Maybe it's rational on some level; if you manage to give the people you prefer limitless power while they rule, maybe they'll become powerful enough to end elections.
edit: of course Moraes did the same for Bolsonaro as for Lula. Some people's ideologies rest mainly on their hatred of the general population, not a preference for the rule of any particular party.
