And that's your criterion, by the way: something has ethical credibility in proportion to how much will power is exerted.
That's not my criterion, that's
your criterion, and I've challenged you to provide a logical proof of that assertion.
Moreover, you have yet to define terms like "ethical credibility" and "ethical credit."
The bottom line is that you're upset because "the cute" have a privilege advantage over the plain and you're trying to find some way to claim that's unethical.
But first you have to prove there is something inherently unethical about an action that advances human survival--and at least within both Utilitarianism and Hedonism, you'd be proven wrong.
Let's modify the Trolley Problem a bit. You've got a runaway trolley car full of people heading for a certain doom collision with a freight train crossing on another track. You stand at a rail switch able to divert the car to one of two safe tracks, but on one of the safe tracks is a homeless crack addict and on the other safe track is...your own daughter.
The constraints of the problem are such that you have absolutely no options other than:
1. Take no action and let the trolley full of people strike the freight train and be killed.
2. Divert the trolley to the safe track that will kill the homeless crack addict.
3. Divert the trolley to the safe track that will kill your daughter.
Now, according to your reasoning, the most ethical option is to divert the train to kill your daughter simply because it's the "most difficult" option.
Prove that.
And you still have to define what "ethical credit" means. I'd suppose it means "how close to a moral agent's desired 'end good' a particular action moves that moral agent," but you haven't told us yet what that "end good" might be.
