Useless, outdated, proves that a lot of humans are just animals and they are greedy and selfish.
Pointless overall, violent, enable monsters to be monsters. To rape, to torture, to enslave, to degrade, to kill.
War shows the discrepancy of morality between people and how our system of living is designed to make money AND NOT to teach people how to be people.
Wars only happen because you are only good for making money once you're 18 and you're expected to just work, go home, eat, repeat with casual vacations to other countries.
You are cheated everyday, there are strings everywhere, when you go to foreign countries, when you buy from your own supermarkets, everything is controlled and you don't have time to learn about it, it's by design. Making learning how to survive a priority means that people are oblivious to the horrors of the world and how the companies, governments, politicians and secret services all over the world control us just like puppets for profit.
Humans know war is bad but they don't know why, if they'd do, they'd go out in the street. It's the same with animal cruelty and factory farming, you probably know that it's bad, do you know how bad it is? have you had an upbringing where you CAN CARE about how bad it is? if both of these are no, then congratulations, you've been brainwashed by design and you will never do anything against animal cruelty; you've been brainwashed and kept in the fog and normalized eating animals that even if you realize it's bad, there is an overwhelming amount of media, an overwhelming amount of support from other humans to just not care and to continue eating animals.
Same goes for war, we all get brainwashed for individualism and to be cog in the machines, "unfortunate fact of life", "they deserve it", "it is what it is". It's all by design, wars are awful, everyone in power knows that and they're trying their best to keep people as dumb as possible for as long as possible (probably until they die of old age). We'll hopefully see many changes in 2040-2050 after every 1960-1990 old relic kicks the bucket
