"Which of my children would you wish I did not have?" There was a sudden silence with no forthcoming reply. I think my fellow employee immediately realized his terrible gaffe and wished he could have slithered out of the restaurant at that very moment. He was quite subdued for the rest of the evening as best I can recall!
Yes, that is always my response when various extended family criticize the number of children my wife and I have had. "So, which one would you like me to get rid of?" [that's a little more direct and blunt than "wish I did not have"] Of those couples who have limited their families, God will ask them at their judgment, "So where is John and where is Therese, the souls I would have desired to bring into existence."? Controlling birth is a greater evil than murder because you're preventing souls from coming into existence. Now, at a layer above this, of course, God uses everything, including our sinful decisions, as a way to direct His providence. But we're still subjectively guilty. So, for instance, if I murder someone, then surely God willed that the victim should die that day, but that does not diminish my responsibility for murder.
