So here's one for the books...About a week ago, I ran a game of Trail of Cthulhu, a case involving a curse passed down from father to son, in which once a son is born, the mother dies in childbirth, and the father becomes a hideous creature, the result of some faustian pact made long ago.
The story begins with an old man found stabbed to death, the only clue leading to a small home where a blind pregnant girl is being taken care of by her brother, since her husband has run away, for reasons unknown.
The players track down the husband, who is in the middle of his transformation into the creature. They kill him, only then to discover that he was killing certain individuals for key ingredients in a means of breaking the curse for good. Instead of trying to find some means of saving both mother and child, they opt to cause a miscarriage by having the mafia member of the group to beat the living shit out of her with a baseball bat.
"She'll live, just gonna kill the baby and end the curse." She reasons, as though that makes me anymore understanding of their decision.
I refused to role-play out the end-result, merely stating with a hint of contempt in my voice that the scene ends with her leaving with a baseball bat over her shoulder, whisteling Zippety-Doo-Dah while en route to deliver a Baseball-Bat-Abortion.
I then made everyone else roll stability checks for their heinous way of thinking.
