if you came across a person in a coma... would you just kill them? they can’t speak for themselves. so why wouldn’t you?
because you make the assumption they would want to live.
i am 100% certain that if you could ask a fetus whether or not it would like to live, i am ABSOLUTELY certain they would say yes.
so how are the two situations any different?
Oh, Boxer shouldn't be killed, just retired.
