Can you clarify why feelings of guilt are important here?

They aren't particularly, but

We mostly don't seem to care.

I thought we were talking about feelings, my mistake. I suppose the point was that I do care if innocent people die, so by extrapolation I assume other people do too.

I mean, I have no idea how much guilt executioners feel.

Please, pardon my rhetoric.

Also, I think got carried away with the whole "guilt" theme - feeling guilt, guilt by assocation...

But how much guilt they feel or don't feel doesn't play much of a role in my decision to support or not support medicine, commuting, law enforcement, military action, or capital punishment.

Only one of those things has the explicit goal of killing people, and it's the only one I'm arguing against here. I'm not too sure what you're arguing for or against or if you're just stimulating conversation, but regardless, thank you for responding to my first comments on LW :)
