Oh no, that would be a thing if indeed I said suffering “for no good reason” was a good thing, or if I denied it is a bad thing. Read my posts carefully and don’t insert words I did not utter into my mouth please. I simply asked on what basis does one say that suffering is bad.
Anyway, suffering for no good reason is indeed bad because… well there is no good reason. Studying for no good reason is bad, eating for no good reason is bad, living for no good reason is bad. Anything for no good reason is bad by definition.
Suffering certainly has existence in the world as implication of free will. You can’t have both fully free will and absence of it’s effects. Suffering is effect of free will. I also do not think you will find completely meaningless suffering in the world. It all has cause and effect- which gives it meaning. I am not saying meaning of suffering is always good or makes suffering worthy to undergo (far from that) but if suffering exists for good reason (such as existence of free will) then no suffering is indeed for “no good reason”. Whatever it is.
