When can a defendant assert self-defense?

However, the law limits who can validly assert self-defense. " 'It is well established that the ordinary self-defense doctrineapplicable when a defendant reasonably believes that his safety is endangeredmay not be invoked by a defendant who, through his own wrongful conduct (e.g., the initiation of a physical assault or the commission of a felony), has created circumstances under which his adversary's attack or pursuit is legally justified.' " (People v. Hardin (2000) 85 Cal.App.4th 625, 630.)
