You have presented very challenging moral dilemma scenarios here! But, I disagree with your view of placing value on lives based on the amount of enjoyment that can be obtained from them :)
Precisely because of what you, yourself, wisely stated here:
All human traits are good for some purposes and a value of an individual to us depends highly on what we can get from that individual, which doesn’t have to be much in according to how good is that individual for the rest of the humanity.😉
❤ Have a great weekend my dear !
