I feel bad only on the most basic level. Over time, you kind of get used to the idea, especially since once you begin to acknowledge the suffering in the grand scheme you realize that untold agony has already befallen millions of people before you were even born.
Then it occurs that every second you waste thinking about it, someone else dies a horrible death, and that even if your generation succeeds in conquering the very nature of the planet, and creates a world where the innocent aren't victimized, that millions more will have died not only in the time it took, but maybe even in the name of creating such a world.
AND that such a utopia would not only be a virtual impassibility, but that it could by no means last forever, and that it's fall will herald the rebirth of the cycle all over again, and that it will only ever end with the extinction of the human race or the destruction of earth itself.
The madness we see before us isn't the result of a freak accident, humanity has known this endless tragedy since it's inception. It is in the very nature of life to suffer, escaping that suffering is what drives it forward. Humanity couldn't have evolved as it did without the threat of starvation, the fear of death, or the resistance to pain, and it is through these things that we create works of beauty, that we learn to show compassion, however little it may ultimately do.
I gave up on the grand entropy a long time ago, and if I were to connect personally to all this, I'm pretty sure it would drive me insane.
Constantly looking at the big picture would rob me of all the beauty the world has to offer right in front of me. Maybe it's only so beautiful BECAUSE I know all the pain that hovers around and through it.
It's all entropy, endless shades of every color in the spectrum, and a short flash of light is all we have, and if we can't find something there in spite of all the dark, we either die in sadness or have all of eternity to regret it.
If I felt as bad as I should about every bit of suffering that surrounds us, the world would be a dark, empty place.
