The process of "killing your babies" has nothing to do with Abortion. You kill one of your babies when you let an idea you love die; be removed from your project at any stage of production.

It is important to kill your babies because they are often ideas that you love but will not help your film. An example was a shot of an angel candle that my director once required that I leave in the movie. It was not needed, and five years later we all agree it should not have been included. It was a pretty shot. It should not have been in the film.
