If we were to somehow fix society, the universe would still show its teeth and death would still wave its hand. Even in a perfect society, humanity still ends. Every path leads to the same conclusion; what you do doesn’t matter once enough time has passed. Just take how big the universe is into perspective, and how small the planet everything we are happens on.
What’s important is what you believe in, and how you feel. I believe the relationships you form and the love you feel will matter long after we are all gone. Sorry, I went off on a rant.
