Here is another issue you have if you take pain out of the equation.
It is simple but overlooked, I think.
See, without pain and suffering, I don’t think our world would look nearly the same.
Would your Grandfather have left for war and even met your grandmother?
How would King David have even shown bravery at some point?
Would you even be you? Would you even exist?
For if you remove a large piece, does the entire thing fall apart?
These questions are not so easily dismissed.
In sum, had the possibilities for suffering in this world been very different, events would have unfolded so differently that an entirely different community of people would have come to exist. Our parents never would have gotten together. They never would have conceived at the precise time that they did. And therefore “we,” as the individuals we are, never would have lived. We often wish we could take some piece of suffering out of the world while keeping everything else the same. But it doesn’t work that way. Changing anything changes everything, and everyone.
