But, I disagree with those who say this. I believe a time will come when bad things not only can be limited, but can and must be completely undone and reversed.
I say, some things are perfectly good, and some things are perfectly evil. The gray area between the two exists only because we do not know everything yet - because some key information are still yet to be uncovered. The goal is to uncover all of it and know its full meaning. I believe this is possible because God (or whatever you want to call it) does not play dice, nature is not malevolent, and everything is out in the open waiting to be discovered by anyone with enough faith to persist in seeking. I believe the goal of removing the gray area - in other words uncovering the truth - is the only goal worth pursuing in life.
I choose to believe this because if this were true - if it is true that all things can be known, and that knowing everything will lead to an unadulterated understanding of good and evil, then it would mean that good things can exist without the bad. It would mean that any harm, not only can be limited, but can and must also be undone. It would mean that anything broken can and must be made whole again, anything corrupted can and must be made with integrity again, anything once dead will live forever, and anything lost will find salvation. It would mean there is justice. And, it will mean that our most noble ideals are not merely dreams, but a reality.
The alternative is to say we must live with both the good and the bad. And for a long time, we may have to. But while I refuse to believe this is a permanent state of affairs, I may be proven wrong in the end. Maybe that's all that there is. Maybe I end up being proven to be on the losing side of the battle. But, I have made my call. I have picked a side. If I lose, then at least I risked everything for the chance to undo harm.
