An advantage of internalism is that it captures the intuitive wrongness of unnecessary force. A disadvantage is that it implies that even culpable attackers may harm their victims in counter-defense, should their victims use unnecessary force against them. If Gunman in Jump is not liable to defensive harm, then any harm he suffers is unjust. It is Victim, then, who seems to be liable to be harmed, should he defend himself rather than jump.
