A lot of stuff to unpack here, so I'll focus on the one that really struck me. The universe is filled with balance, every aspect has an equal amount of opposites to balance them out. Matter has dark matter, light has dark, and so on. Ridding something of the negative aspects wouldn't work as there is always something that would take its place. Law of conservation of energy and all that. As @therealpaul put it, we are all energy anyway, so I guess that's why it effects us. We just have to be more compassionate so that we could strike that perfect balance.
