By all means, give the patients whatever care you can to make them as comfortable as possible. But killing a patient is wrong.
The truth is, you cannot know whether help is on the way or whether a patient is going to die.
Sorry, when someone is terminal, in obvious pain and suffering and the limited resources available must be conserved, for unknown and indefinate times because society has literally collapsed. The rules have changed.
Society allows many excesses and privaleges that lack of it does not.
When society collapses, you are left with survival. If a bed or drug or whatever is needed for a patient that can be saved it is not wasted on one that cannot be.
It may sound cruel, but that’s how life is. This doctor did nothing wrong under the circumstances. If you believe he betrayed Gods law then he will face God’s judgement at the end of his days. He should never have been charged under mans law given the circumstances they were working under.
