Wave goodbye to the Golden Rule!
The Golden Rule is apparently not a New York value.
Actually the Golden Rule requires a sound foundation moral standard by which you rightly decide what you would want done to you. Without which many immoral things may be justified. A suicidal person would kill another based upon a wrong idea of what he would have done to himself.
But here, the tow truck driver could reason that if he was going to make a wrong decision, then he would want someone to not enable him but correct him, even to not helping him out of a temporary situation so he could think. Of course, helping your enemy in such a situation of merely enabling him to drive home is a Christian response. But what if you knew the person was on his way to get an abortion?
