The assumption there is “I have an idea of what the designer would/should have otherwise done”, which is a little difficult for me to accept on face-value - especially from someone who doesn’t think such a designer exists.
The assumption is different. It is: “I have an idea of what a
rational, all-knowing, all-powerful and all-benevolent designer would/should have otherwise done”. Whether one actually believes that there is such designer / creator - is irrelevant. It is just a thought experiment.
From the all-knowing aspect it follows that this hypothetical designer knows about the pain and suffering.
From the all-powerful aspect it follows that this hypothetical designer can remove all the pain and suffering, except those which would lead to a logical contradiction.
From the all-benevolent aspect it follows that gratuitous pain and suffering could not exist. Pain and suffering could exist if that pain would be logically necessary to achieve some specific greater good, which could not be achieved if that pain and suffering would be removed, or even lessened even a miniscule amount.
Of course you try to have your cake and eat it, too.
There are two, diametrically opposite defenses against the “problem of evil”. One is the “free will defense”, which says: “the (nearly) unlimited free will is so valuable in the eyes of the designer, that gratuitous evil is accepted as a corollary of the freedom”. The other one is the “greater good defense”, which says: “there are SEEMINGLY gratuitous evil events, but they are really not gratuitous, because they are logically necessary to bring forth that unspecified, nebulous greater good”.
Neither of them “works”. The unlimited free will is only valuable in the eyes of an evil or indifferent designer. The greater good defense is an empty proposition, UNLESS the apologist can establish that every piece of suffering is logically necessary to achieve that specified and “greater” good. Which leads to the necessity to have a valid and sound argument to establish both that “greater” good, AND that removing a miniscule amount of the suffering would jeopardize that “greater” good.
It is childishly simple to see that the amount or suffering shows a decline with every advancement of medical science.
So the apologist has no defense.
Moreover, it is also childishly simple to design a world without pain and suffering. Use heaven as a prototype.
