What is justifiable homicide under the doctrine of reasonable resistance?

A homicide is justifiable when a defendant reasonably believed he or she was in imminent danger of suffering bodily injury, reasonably believed that the immediate use of force was necessary to defend against that danger, and used no more force than was reasonably necessary to defend him or herself. (People v. Humphrey (1996) 13 Cal.4th 1073, 1082; People v. Villanueva (2008) 169 Cal.App.4th 41, 49-50.) Such lawful resistance can be made in defense of another. ( 197, 692, 693, 694.) Under the doctrine of defense of another, reasonableness is tested from the point of view of the defendant, not the person being defended. (People v. Genovese (2008) 168 Cal.App.4th 817, 830, citing People v. Randle (2005) 35 Cal.4th 987, 999-1000.)
