One could certainly debate the morality of the choice of how to kill:
But torture was allowed by the Church at one time but now torture is taught to be intrinsically evil, No? Would this not be an example of a change in the moral acceptability of what is intrinsically evil, or taught to be intrinsically evil during a certain time period?
Torture: today taught to be intrinsically evil.
Torture: Hundreds of years ago, torture was taught to be morally acceptable and burning alive at the stake was used in the papal states with the approval of the Pope.
Now we have the question of artificial birth control.
Artificial Birth control: today it is taught to be intrinsically evil.
Can the teaching on the moral unacceptability of ABC ever change? People here say no because ABC is intrinsically evil, so the teaching cannot change. But OTOH, we see that there has been a change in the moral acceptability of torture, even though it is now taught that it is intrinsically evil.
To sum up:
If the Church can change its teaching on torture, does this set a precedent for the possibility of a change in the teaching on artificial birth control ?
Or, is there some sort of flaw in this argument?
