I think I've seen both sides. I no longer suffer very much, because I largely recognize the ego self as a delusion. However I experienced intense suffering when I was young. While suffering may not be real in an absolute sense it is very real for those who still cling to themselves.
I don't see any way to justify that suffering just so that some can experience joy and happiness, which as far as I can see have no true inherent value.
Not everyone sees life as unending torment.
