Suffering often occurs when good and evil approach in opposition. I don’t agree with people who believe that suffering should be sought out on principle, because it seems to need no help to occur — but if humanity shied away from all suffering, it would be shying away from many occasions where good can otherwise press through evil.
I think there is some biblical justification for seeking out suffering. Look at Christ and his 40 days in the desert. There are times when it can be profitable to the Faith.
