The animal world is cruel. Animals actively eat the babies of other species. Animals rape each other, fight each other, and let each other starve.
Are humans shitty? Depends on what we're comparing it to. We've displayed a pretty incredible amount of growth and compassion amongst ourselves as we've evolved of the struggle for survival. Sure - shit sucks. Sure, the media is designed to show you the worst of the worst to get you outraged and addicted. Sure, we could be better.
But poverty, violence, and homelessness is on a steady decline. We are starting to see widespread gender equality for the first time in... maybe ever. We are able to keep our children alive so much that our population is BOOMING.
If you compare where we are now to the rest of history, we are the kindest we've ever been.
Sure, if we compare us in the past, we're better today then ever, but there's a lot of injustices between poor and rich. Money create a lot of problems. These problems continue to exist today and will exist in the futur too. Btw, thank you for your comment and yes there's a lot of good things today who doesn't exist in the past like you mention!
