On several threads the problem of evil comes up. The theist defense to this problem is that even God, with his omnipotence cannot bring forth all the “good” things without allowing some evil to happen.
There is a usual allegory to highlight this question: it speaks of a child who suffers from a serious health problem and he must undergo some painful medical treatment to cure him.
The child cannot understand why he is subject to the painful medical procedure. He cannot comprehend that it is necessary to allevite his condition. It is morally permissible to expose the child to the pain and suffering of the medical procedure, because the greater good of curing him and the painful procedure form a morally justifiable set of actions. (Important observation: the greater good of curing the child does not justify the procedure, in and by itself.)
This allegory looks great on the surface, but it proves to be false under scrutiny. It presumes that medical technology cannot be improved - that is the pain involved in the medical procedure cannot be lessened. It presumes that child’s ailment is a given. None of these apply if we consider God’s omnipotence.
So I ask you to present an example, where God wishes to bring forth a “greater good”, which is impossible to do without inflicting / allowing some “evil” to happen.
It does not matter how “farfetched” the scenario is. It does not matter, if the “greater good” materializes in this life or in the afterlife.
The only restriction is that the sufferer and the beneficiary are the same. This is essential. It would be morally impermissible to use a human being as a “tool”, or as a “means” to bring forth some good that benefits only others. Basic Catholic teaching asserts that human dignity prevents from using a human being as a “resource”.
I tried to come up with a possible scenario, and so far I failed. So I am passing the “baton”. Can anyone come up with an example?
