It's interesting that as humans we deeply know that things like love, beauty, hope, peace, and such are good things. We see them as the standard. The default position so to speak of how things are supposed to be.
How do we deal with the cruelty? On one hand we can imagine a world where we somehow internally become motivated enough to never again harm one another or do more damage. But to be honest the force of evil itself has to be dealt with.
The tendency and urge to do harm to one another has to somehow be removed and replaced with a much more powerful force than just human will.
