I fail to see how this is “uncivilized”. Unpleasant perhaps, but no more uncivilized than plumbing.
I think the distinction here is between moral and practical reasoning, not civilized and uncivilized reasoning.
Of course, there’s all sorts of questions of method and duration and whatnot that we could argue about ’til the sun goes out, and if the species survives that long in a remotely recognizable form probably *will*.
It does reduce the person to the status of an affliction: something to be cured, and then ignored.
