I have truly, authentically have uncertainty around this and even the idea of “free will” (I’ve audited the Stanford class by R. Sapolsky who makes the case there is not free will as we think of it). Even if evil, good and free will were discounted it seems, as even Sapolsky acknowledges, that suffering exits. Separate from epistemological theories my conviction is the most meaningful thing I can do is to pay attention and reduce suffering for all that I perceive surrounds me.
