Death is a natural, and essential part of evolution, and is crucial for the survival of the species.
If you could magically save everyone from dying tomorrow, then well done! You've just killed everyone from overcrowding.
Since your basis for morality seems to be "evolution" and "nature" (in quotes), would you be in favor of shutting down all hospitals immediately?
Wow. That's ultra-elitist.
So, let's say you are diagnosed with a rare disease and the doctor gives you two weeks to live unless you get a medicine that costs $1000 which let's assume you can't afford. And you're going to die someday, anyway. Does that mean you have a shitty life and you deserve to die now?
So, amount of money = value of life? Is that your point??
So, I own 10x more money than you (assume) and hence compared to my standards, I think you live a shitty life and you deserve to die. How do you feel now?
Life is invaluable. Money has nothing to do with it.
