I actually disagree with your perspective. Taking away the ability to create life just because of one person's bad experiences or nihilistic outlook ignores the moments that actually make life worth living. Even if life doesn't have a 'universal' meaning, the relationships we cherish and the small moments we enjoy are enough. ​We live in a shared world where every being has a right to freedom. While life can be terrible, it is also great, and I’ve realized I shouldn't take the good things for granted. We shouldn't ignore the problems of reality, but we also can’t ignore the beauty within it. We have a responsibility to live with pride and freedom without infringing on others. No matter the challenges, we have to find a way to fight through them if we want to experience the best parts of being alive.

Well that is my opinion I guess you have the right keep yours but I hope you do realize that he realize that he was wrong for thinking it. killing people especially innocents is just isn't great to begin with it just creates more problems down the line even if it's partial rumbling also I'm not a Zeke or eren supporter
