I don't keep saying that you're begging the question, I point out that you're begging the question, point out how you're begging the question, and provide an example of the question amended to correct the fallacy.

You need, if you're going to insist on an answer to your question as you're asking it, to begin with a prologue along these lines:

"I reject the Church's teaching on abortion. I also reject the Church's teaching against the use of situation ethics in moral analysis of objectively immoral behavior, such as abortion. In my moral analysis, performing a body count can be used to weigh the morality of an act."

That statement is implicit in your question - thus begging the question - but you absolutely refuse to admit it.
