Granted, what I find odd is when the pain does not motivate us to stop what is causing the pain. So that we could have the pain but just repeat the same stuff as if it will be different the next time. Pain allows us to know better perhaps, but knowing better isn't always enough to stop us, like we are just glutton for punishement. We could even predict, based on experience that something will cause suffering but then we do it anyways, we just sometimes try to handle it then regret when it is too much when comes time to bare it. Wondering why we would do such a thing in the first place, likely from lack of wisdom, not using the knowledge we have to the greater benefit.
If there is a God, He keeps making new humans that way.
It is the real "Problem of Evil".
If I become God humans will be born with an instinct to find the truth stronger than the instinct find sex.
