when i say that it's depression turned into philosophy i mean it in the sense that it is a philosophy that will inevitably lead to depression, or at the very least a skewed world view (think you'll see a red car and you're going to spot a lot of red cars, think existence is suffering and you'll probably focus on suffering a lot).
interesting breakdown tho, i'm glad that you still have hope. i dislike antinatalism and similar philosophies mostry due to their "doomerism" and belief that experiences are somehow cumulative
you do understand that the joker is in the wrong here, right? like in this scene he's a mentally i'll man saying that killing people is funny.
if you genuinely believe that existence has an inherent negative value then i strongly suggest you seek help, and i don't mean that to be facetious. antinatalism is depression turned into a moral philosophy, it posits itself as a solution to suffering by offering an unrealizable future, but really it's an excuse to not even attempt to make the world better.
4chan would have thrown in some slurs too
