Assume a royal arranged marriage is taking place, essential for reasons of state, and accepted by the couple, but with no attraction or liking between them. Is it ethical to dose both of them with love potions so they can have a happy marriage?
Yes, if they both give informed consent
Yes, if the potion won't reduce their effectiveness as rulers
No, true misery is better than false happiness
No, using love potions never ends well
