I would say the opposite is true, sanity and integrity can't prosper much without one another. Everybody dies, at some point, and to give up oneself to live in infinitely short amount longer (compared to eternity) is shitty a consolation price for those who don't really have themselves to begin with, who were compromised in childhood or youth, and live the rest of their lives slapping rationalizations on that.
> Of course it is "more useful" to commit an injustice than to be victim of it; for the sake of the thinking dialogue with myself, this point of utility must be abandoned.
-- Hannah Arendt, "Wahrheit und Politik"
> Natürlich ist es "nützlicher", Unrecht zu tun als Unrecht zu leiden; um des denkenden Dialogs mit mir selbst willen muss gerade dieser Nützlichkeitsstandpunkt aufgegeben werden.
