Same thing, Haruka and Michiru ruined S for me, they were basically bullies, and if they didnt changed their ways at last episode of S, if i were Sailor Moon/Serenty, i would take their powers away, they are too dangerous. Like Makoto said, they were no different from Daimons. At least in Crystal/manga they felt remorseful for their action and knew even if Hotaru dont have much time left, killing her is still bad, but they have to get their hands dirty, even if everyone else will hate them.
