I don't know if pain is bad, but it's definitely something I don't like and want to avoid. I'd much prefer a warning and alert mechanism that doesn't feel so subjectively awful, and that doesn't misfire so much.

I don't know if I'd want to have congenital insensitivity to pain, but I'd like to "cap" my sensitivity to something much less than it currently is.

Eliezer has written about this, too.
