Every person has the right to defend himself against unlawful force. He may use deadly force only to prevent a dangerous felony. No excessive force is not privileged. If the victim of the initial aggression suddenly escalates a minor fight into one involving deadly force, without giving the aggressor a chance to withdraw, the aggressor regains his right to self-defense. There is no duty to retreat in such circumstances.
Deadly force is justified if necessary to prevent commission of the act.
There is no right to use deadly force solely in defense of property or for prevention of a nondangerous felony such as larceny.
