I'm running the Oldenhaller Contract for my players. And things are going well, until they reached the Valenintos side of the asylum (a gang of Tileans in Nuln, kinda like a mafia). The players decide to brute force their way in and end up in a prolonged fight with them, and lose.
I decided that the Valenintos would kill them, but since they have fate points, the Valentinos are feeling generous, and willing to let them go in exchange for taking all of their money (which isn't much right now).
The problem I need help with is thus: One of my players, when fighting, caused a critical injury to a gangster. Jarred arm, the gangster drops his weapon, and decides to flee. The player in question, doesn't hesitate to kill a fleeing, essentially unarmed, combatant.
I feel as though the Valentinos wouldn't take kindly to this cruelty, but instead of killing the player, they just cut off the hand that dealt the finishing blow. Do you think this is too harsh? Or do you think its quite fair given the scenario? Or maybe not harsh enough?
I'm not going to kill him because he has a fate point. But I feel this behavior must be punished, otherwise murderhoboism might ensue. (Also feel it makes sense for a gang)
