I appreciate the comment, forgive my late response.

I agree that "kill one another off" was a bit hyperbolic, but it was past the edit window before I noticed that it was being genuinely misunderstood. All I meant was what would seem to be happening: People exposing one another to a communicable disease with a death rate of X. I was arguably using the wrong terminology for the magnitude of X.

Whether a death rate of X is acceptable or not may depend on social acceptance of the cause, the visibility of the cause (plane crashes always make the news, suicides don't) social class, etc. This is evident in the use of analogies within this sub thread, as a way of trying to make sense of the issue.
