Here are my thought about this, but these are only my thoughts and I don't know for sure if they are Theologically right or wrong..
I think a case can be made in SOME situations
Take for instance, if the Chinese Government allows factory workers to handle materials that are known carcinogens and many workers get cancer because of this. It seems to me that the Chinese Government is following satan and his minions in being guilty of causing cancer.
Now , that said, satan does not win because the poor chinese worker has had cancer forced on him. I believe that Jesus will save the poor as is written in the beatitudes-Blessed are the poor.
Our Lord is especially merciful to the poor of this world
You STILL don’t want to say that Satan can retract his own caused cancer; do you!
