That's a slippery slope. Who gets to decide who lives and who dies? Who should we abort or sterilize? We all suffer to some degree, then we all die. It's the human condition.
Doctors do all the time, they even have their own word for it: triage. When resources are insufficient to cover the needs of everybody, difficult decisions need to be made. Or as the case may be, easy decisions...
People is classified in colors black, red, etc after its state. If you are in an accident and you cry and shout repeatedly you are classified in a lower priority than the quiet person that do not moves.
It's where we draw the lines on this slippery slope that constantly evolve.
