****** : ENFJ probably dominant ? Or Ni subtype. Was ****** healthy ? Possibly. I don't know after all if healthyness is related to morality. The story of ****** is quite coherent to how he developped, and aside at the end where he became paranoid, he was very active all his life. Perhaps some could say he was even very healthy. This is not especially my POV, that's I POV I wanna test. The relation to healthyness and "good" morality.
Nietzsche ubermensch, untermensch, evil : It could be projection that don't relate to type, but that each type could be in some way. If some can developp this view I would be happy.
If we was looking for type absolutely, I would say :
Ubermensch : either ESTp or ESFp
Untermensch : either INFj or INTj (notice I'm untermensch, what a cool knowledge to have. Basically feeling now the worst kind of stuff in humanity)
Evil : ESTj
