If you actually care about understanding the religious perspective on this, read the Book of Job.
The whole premise of "God decided to show Satan (why God thinks he need to prove anything to Satan in the first place?) his point by tormenting some mortal is... sadistic at best ?". And doesn't really touch topic of "why someone is allowed to be tortured by disease from birth and dies due to no action of their own will".
Though, in just a non-religious who grew up Christian, so this is all for fun and games.
