Hi Mark
I've missed your post for a while, then I decided that it deserved a thorough answer, then... It's nearly one month since your post!
I'm leaving for some vacations, so I afford it when I'll be back.
One shortcut I find playable (in front of similar huge ethic doubts) is that I would suggest players to seek the response - which is the Good choice - from some god (of Good).
But I'll come back on it later.
Thank you for the example.
Ale
