Did these medical personnel play God?

Triage is more for the purposes of allowing death to take it's natural course so that attention can be focused on others with a better chance of survival.

In other words, they had the right not to treat them, but not the right to take life from them.

The Hippocratic Oath seems to contradict some of this, but I think its contextual use is if a patient is already dying. Giving them an overdose of morphine, for instance, or having them die on an operating table, is basically the doctor's responsibility, but not really his fault.

Jam it back in, in the dark.
