The question is why do good people endure more ?
The suffering Jesus had was more than we can imagine. There were 2 other thieves who suffered at the same time but why should a pure person suffer
This is difficult to answer in public. The process is quite complex. A sign of progress is greater endurance to suffering as progress is made
Some of it is dissolve karma to be with God. You can never be with God till all karma is dealt with completely.
But tremendous progress is made of the difficulties are dealt with , with a smile and a reminder , God let me see you once before my final breath
