I think that the way mind control is implemented isn't great, but that it could be implemented in a way that presents interesting choices for the player (think like the "do this or else" mind control design of the Guild Wars 1 Mesmer which had you constantly weighing whether it was better to obey or disobey and face the consequences), or in a way that basically makes it feel more earned (e.g. you don't save or die, multiple things have to go wrong for you to die. Mind control could be designed the same way).
