Sorry, beg to differ. If it is within your power to assist, and you refuse to do so, then that is, by any moral standard, murder. In much the same that, for instance, you are standing on the pier. Some one is drowning right in front of you. There is a lifesaver ring next to you.

You look at them, Look at the ring.

And walk away.

To me that is deliberate murder.
