Holden, I'm curious where you would put painist organizations - those who are only trying to reduce / alleviate pain. One Step for Animals and Lewis' Open Phil work are along these lines. Or do you think this is not a big enough area to warrant discussion (which could well be).
I have serious doubts about inter-personal trade-offs.
