To me, that is a whole person change. To go from "I can't judge others" to "It's murder and it's wrong." was a significant change in my heart, mind, and soul.
It is, however, my opinion that we are made pro-life, some of us become "pro-choice", and then we may become pro-life again.
Please understand that this is in no way a criticism of you, but I think the entire "I wouldn't do it, but I also wouldn't try to stop somebody else from doing it" attitude is bullsh*t. As you said, you eventually came to see that it was murder and it was wrong. However, it was ALWAYS murder. Many have succumbed to the moral relativism/libertarian nonsense that "it's none of my business what somebody else does." However, if you saw somebody aiming a gun at somebody else and they were about to kill them, to pretend it's none of your business is morally wrong.
