the aider and abettor’s intent may be made by way of an inference from her volitional acts with knowledge of their probable consequences.
Thus, we conclude that the weight of authority and sound law require proof that an aider and abettor act with knowledge of the criminal purpose of the perpetrator and with an intent or purpose either of committing, or of encouraging or facilitating commission of, the offense. (People v. Terry, supra, 2 Cal.3d at p. 402; People v. Yarber, supra, 90 Cal.App.3d at pp. 915-916; People v. Vasquez, supra, 29 Cal.App.3d at p. 87.)
When the definition of the offense includes the intent to do some act or achieve some consequence beyond the actus reus of the crime (see People v. Hood (1969) 1 Cal.3d 444, 456-457 [82 Cal.Rptr. 618, 462 P.2d 370]), the aider and abettor must share the specific intent of the perpetrator. By “share” we mean neither that the aider and abettor must be prepared to commit the offense by his or her own act should the perpetrator fail to do so, nor that the aider and abettor must seek to share the fruits of the crime. (See People v. Terry, supra, at p. 401.) Rather, an aider and abettor will “share” the perpetrator’s specific intent when he or she knows the full extent of the perpetrator’s criminal purpose and gives aid or encouragement with the intent or purpose of facilitating the perpetrator’s commission of the crime. (See People v. Terry, supra; Model Pen. Code, § 2.06; generally, Perkins, Criminal Law, supra, at pp. 662-663.) The liability of an aider and abettor extends also to the natural and reasonable consequences of the acts he knowingly and intentionally aids and encourages. (People v. Beltran, supra, 94 Cal.App.2d 197, 207.)
CALJIC No. 3.01 inadequately defines aiding and abetting because it fails to insure that an aider and abettor will be found to have the required mental state with regard to his or her own act. While the instruction does include the word “abet,” which encompasses the intent required by law, the word is arcane and its full import unlikely to be recognized by modern jurors. Moreover, even if jurors were made aware that “abet” means to encourage or facilitate, and implicitly to harbor an intent to further the crime encouraged, the instruction does not require them to find that intent because it defines an aider and abettor as one who “aids, promotes, encourages or instigates” (italics added). Thus, as one appellate court recently recognized, the instruction would “technically allow a conviction if the defendant knowing of the perpetrator’s unlawful purpose, negligently or accidentally aided the commission of the crime.” (People v. Patrick (1981) 126 Cal.App.3d 952, 967, fn. 10 [179 Cal.Rptr. 276].)
Both the instruction suggested by Yarber, supra, 90 Cal.App.3d 895, 912 (“A person aids and abets the commission of a crime if, with knowledge of
