Another caveat of pain vs. suffering is that suffering is an abhorrent compass to begin with, for you can't reliably test and interface paths of suffering as well as those of pain - which are fuzzy, too.

e.g. "I suffer in Socratic dialogue, therefore I... should double down on sophistry" is a common case, certainly an adaptation to believed suffering, but it's anything but individuating. You can't always get a bird's eye of your qualia to have deeper insight on what you feel from why and what'd be sensible, so your rely on what you take as the compass. At some point you won't even be sure if you're suffering or not, at the moment, generating its own suffering. Imagine a compass that spoofs itself.
