Does a jury need to be instructed on the definition of manslaughter and the doctrine of unreasonable self-defense?

special circumstance establishes here that the jury would have convicted defendant of first degree murder under a felony-murder theory, at a minimum, regardless of whether more extensive instructions were given on second degree murder"]; People v. Koontz (2002) 27 Cal.4th 1041, 1086-1087 [any error in failing to instruct the jury on the definition of manslaughter and the doctrine of unreasonable self-defense harmless, as jury necessarily rejected the unreasonable self-defense theory in returning a true finding on the robbery special-circumstance allegation].)
