What I meant was that bad things will always happen simply because we’re so many humans and a few bad ones will always exist, not because it’s some sort of natural thing we can’t stop. I absolutely agree that we can, and should, always work to make the world a better place. Religion might help you stay hopeful in that aspect but it doesn’t help you in actually doing something to make that happen. Without a god, all issues are caused by humans, which also means that those issues can be fixed by humans. On one hand, it means that we need to do everything ourselves and don’t have someone or something helping us but on the other hand, it also means that we can fix everything ourselves and we don’t actually need any help.
