The "rebuttal" was that ethics is not just a simple question of numbers.
My question to those who remain here is, why not?
One person's death is significant I think.
Many persons' death is also signficant.
One person's quality of life is significant.
Many and many more persons' quality of life is also significant.
Ie. I participate in a church life as a Christian which I share with millions of others on every continent. We enjoy a high quality of spiritual, practical, and moral life in view of our Lord and Savior Jesus Christ.
I think that multitudes on the five continents enjoy this experience communally is significant. But I would also regard it as a high life quality matter if only one, two or three people on the whole earth were experiencing Jesus Christ.
That's on the positive side for us. On the negative side, either one wrongful death or many, many wrongful deaths together are both significant.
That MORE people are involved as opposed to LESS people are involved?
It is not too cut and dry to me. I think the particular case could be considered.
I see no reason to think either more or less in some binary sense flick on Yes or a No. And assigning some threshold exact number would be hard as to WHEN a death has "turned on" or "turned off" the significance switch.
