To say they we the same is of course an exaggeration.

If a man is starving and you don't feed him, then he dies are you responsible? By your line of thinking I would say you are responsible for his death.

Another interesting thought experiment:

A mother and her 1 year old find themselves lost in the woods on a cold night. The mother realizes that she can stay with her child and they will both die or she can leave the child and she will live.

If she leaves the child is she a "murderer"?

This is an example of "abortion" imo and although it is tragic I don't think the mother should be punished as a criminal.
