A limited freedom of actions is much more preferable to the almost unlimited freedom to cause pain, suffering and mayhem.
Preferable to what? For whom? Technically speaking we do not have “unlimited” freedom in that regard- we have full free will (we can want anything really), but we do not have all opportunities in the world. Will and ability are different things after all.
The pain must be logically necessary to achieve that desired “gain”. Each and every one of them. If that pain could be lessened or eliminated while keeping the same beneficial result - then the unnecessary part was gratuitous - and as such “evil”.
That is if we only take outcome into account. How we reach something is much more important then if we reach something. Way is more important than the goal. You see this not only in real life but also in stories, in games and such.
It would be your job (or that of any apologist) to show that each and every suffering will result in some “greater good”, which could not be reached, if the pain would be lessened or eliminated.
Not entirely. My point is that suffering already exists as byproduct of our free will hence each and every suffering has already served it’s purpose (or rather, because of that good there may be byproduct of someone wishing a bad thing and acting upon that wish).
Or you could examine the Holocaust, and show the “greater good”, and also show that if even one death in the gas chamber would have been eliminated, that nebulous “greater good” would have disappeared, too. This is a tall “mountain” to climb.
If you could prevent Holocaust but price would be that no one would ever be able to “want” or “will” anything, would you do it? It’s a strawman same as your position. We were given responsibility over things that do not matter so we might grow responsible about things that do. If indeed what matters is what comes after this life, then death is indeed not a high price to pay, neither is torture. To speak in parable, death and torture to those who have experienced pain in the afterlife is like child feeling pain when parents slap them in comparison to those being brutally tortured. Child thinks it’s the worst feeling ever and other children might as well think that too… but that is because they do not know what real pain is. Same way, we have no idea what real “pain” or “suffering” are. If we measure things by this world alone then yes, one can not excuse suffering nor any sort of discomfort… but that is not how we would measure things.
With things like God, pain, suffering and so on you need to look at bigger picture. You can’t life isn’t fair because you fell of a bike once, and you can’t say life isn’t fair because someone else did. You can’t say God isn’t omnibenevolent because he doesn’t prevent people falling off bikes… and same way, any earthly suffering is not end of the world really.
