Agree with your post.
I remember a really terrible video I watched here about an autistic violent (and self harming) kid and how his mother talked about it. Really shitty, unnecessary suffering that case, and those like it.
Pain and misery have known to inspire a lot though, and many times from the ashes of disasters better things were built. Suffering is powerful because it stirs and speaks to our most deep rooted fears, it gives motivation and pushes people into action, creation, adaptability. But the best things come out of suffering when we fight against it, imo.
