How much liability does a defendant have against a party who aids or abets a crime?

Liability for a crime falls on those who directly commit the act constituting the offense as well as on those who aid or abet in its commission; all are liable under the law as principals. ( 31.) One who aids or abets a crime is not only guilty of the crime he knew his confederates contemplated but also of any other reasonably foreseeable offenses they commit. (People v. Croy (1985) 41 Cal.3d 1, 12, fn. 5.) In other words, a defendant is liable for all the natural and reasonable consequences of acts he knowingly aids or encourages. (Ibid.)
