Reference the post you want me to respond to and I will.
You omitted reply to the following Posts, or replied superficially at best. I include some commentary for context and to assist you to find them:
#755, 768, 774, 804 Which introduces a different mode of death - electrocution instead of death by trolley; The only distinction you can draw is that electrocution kills immediately and a hurling trolley takes a few seconds. In both cases - the end in terms of morality to which the chosen act is inherently directed includes killing someone (and saving others); In neither case does our actor desire that anyone die; The idea that intentionality varies according to how the switch kills (in the 2 cases) is just absurd.
#766 and #777: Which draws your intention to the distinction between direct vs indirect abortion according to what act (medical procedure) is chosen; Do you still claim that all treatments of ectopic pregnancy are “direct killings of an innocent”?
#784: Circular Trolley and the distinction between it and the OP and between actions in that case and Euthanasia.
#803: Proximate is not about timing.
#809: Moral Objects rely on moral content in the description of acts, not merely physical events / process. As JP II writes:
“If the object of the concrete action is not in harmony with the true good of the person, the choice of that action makes our will and ourselves morally evil,…” You describe objects as purely physical, eliminating any capacity to judge goodness.
In VS 74. JP II asks, “What is it that ensures the ordering of human acts to God? Is it the intention of the acting subject, the circumstances… or the object itself of the his act?” And in VS 78: “The reason why a good intention is not itself sufficient, but a correct choice of actions is also needed, is that the human act depends on its object,
whether that object is capable or not of being ordered to God…” How do we conclude whether “Throwing a Switch” is capable of being ordered to God, our ultimate end?

Do you see? - you must identify the end(s) in terms of morality to which the act is inherently ordered if the goodness of the object is to be judged.
