Not to defend feudalism, but the total detachment from morality we see is more of a modern phenomenon. While I’m not going to pretend the Habsburg had an inkling of genuine respect for the lower classes, part of the reason for the power of the church was a shared belief or at least need to pretend to a belief system in which your excesses were bad. The ruling powers of feudalism did just as much virtue signaling, if not more. Things like kings pretending to wear hair shirts under their silks, engaging in performative displays of humility to the church, or isolated displays of charity, were all things the aristocracy did to show their virtue and justify their own rule.
