Negligent Useful: Anish negligently forms the false belief that Vania has unjustifiably pushed a boulder towards an innocent person. Vania in fact poses no threat to anybody. Anish pushes Vania in front of the boulder in an effort to stop (what he believes to be) her unjust threat, which will harm Vania to degree H. (Based on similar cases in Quong 2020: 98–99)
