A person is legally accountable for the conduct of another when:
   (A)   Having a mental state described by the section defining the offense, he or she causes another to perform the conduct, and the other person in fact or by reason of legal incapacity lacks such a mental state;
   (B)   The statute defining the offense makes him or her so accountable; or
   (C)   Either before or during the commission of an offense, and with the intent to promote or facilitate such commission, he or she solicits, aids, abets, agrees or attempts to aid, such other person in the planning or commission of the offense. However, a person is not so accountable, unless the statute defining the offense provides otherwise, if:
      (1)   He or she is a victim of the offense committed;
      (2)   The offense is so defined that his or her conduct was inevitably incident to its commission; or
      (3)   Before the commission of the offense, he or she terminates his or her effort to promote or facilitate such commission, and does one of the following: wholly deprives his or her prior efforts of effectiveness in such commission, or gives timely warning to the proper law enforcement authorities, or otherwise makes proper effort to prevent the commission of the offense.
