What is the test for determining whether a criminal act was a natural and probable consequence of another criminal act aided and abetted by a defendant?

"The determination whether a particular criminal act was a natural and probable consequence of another criminal act aided and abetted by a defendant requires application of an objective rather than subjective test. [Citations.] This does not mean that the issue is to be considered in the abstract as a question of law. [Citation.] Rather, the issue is a factual question to be resolved by the jury in light of all of the circumstances surrounding the incident. [Citations.] Consequently, the issue does not turn on the defendant's subjective state of mind, but depends upon whether, under all of the circumstances presented, a reasonable person in the defendant's position would have or should have known that the charged offense was a reasonably foreseeable consequence of the act aided and abetted by the defendant.
