If you actually want a serious answer to the original question, Christian theology makes clear that humans are responsible for their own downfall:
‘The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness’ (Rom 1.18)
Therefore suffering can be seen as punishment that people incurred onto themselves ever since the banishment from Eden:‘God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another’ (Rom 1.24)
Simply speaking, the Christian God is not actually benevolent in the sense that most are considered damned except for the few that he has chosen to save. This is made clear as ‘grace’ is a special thing for the few, otherwise it is not special and cannot be called ‘grace’.‘Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. They have become filled with every kind of wickedness, evil, greed and depravity.’ (Rom 1.28-29)
Suffering for general mankind is due to their rebellion, but for Christians it has different reasons entirely. I cba explaining that part cos that affects the minority.
