quoted text by Eliezer: If you would balk at killing a million people with a nuclear weapon, you should balk at this.

I must be missing something because this sentence,for me,makes no sense. Why? Why is killing a X of sentient simulations of humans, just as bad as killing X of actual humans. What am i missing? I believe i have counter arguments for this, but would first like to make sure why you are arguing it is so. So i would know we are talking about the same thing and not past one another.
