I have come to the tough conclusion that most people are evil and that includes myself. We kill, subjugate, and oppress other species of animals and our fellow humans for no reason other than convenience. It is more convenient to purchase products made from slave labor than it is to take a moment to seek out ethically produced clothing or electronics, or just buy them second-hand. It's socially acceptable human slavery.
And then there are upwards to 2.7
trillion (2,700,000,000,000) individuals of other species who are directly killed every year because we want to feast on their flesh and their bodily fluids. And that's without counting the indirect killings caused by crop production, deforestation, and bycatch.
I'm trying to do better but it's really hard. Even though I try to only buy products produced ethically and without killing and abuse, it's almost impossible because of how widespread humanity's apathy to harming others is.
I agree, we are the only species that assaults and murders each other and kills their young out of sadism, that I know of. Sometimes I wish I was born as another species. Life would be much simpler, even if I was a wild animal who had to deal with predators and other difficult things. Other species harm each other for a purpose, like food, but we just do it to be cruel and it isn't natural, and doesn't make any sense. Some of us are just evil
As much as I hate being a human, it is far preferable to being a wild animal. Living in constant fear your entire life only to end up being eaten alive by a predator or eaten from the inside by a parasite hardly seems like a simple life to me. I wouldn't want to be a domesticated animal either. Most domesticated animals are subjected to extreme horrors that may even surpass that of wild animals.
Also, many species of animals (such as dolphins) kill and harm others for no reason other than the enjoyment of it. Sadism is a part of nature and is present not only in humans but also in other animals.
