Nope, but if we did the average health of the group would increase.
That’s just a fact, the same as if we shoot all short people the average height of the survivors would go up, and if we kill everybody over 40 the average age of the population will drop considerably.
Doesn’t mean those who recognize these facts are proposing them as policies we should implement.
Similarly, a side effect of keeping alive those who would otherwise die is that the average health of the group drops.
