(a) In any prosecution for criminal solicitation or conspiracy in which the crime solicited or the crime contemplated by the conspiracy was not in fact committed, it is an affirmative defense that, under circumstances manifesting a voluntary and complete renunciation of the criminal purpose, the accused prevented the commission of the crime.
(b) In any prosecution for an attempt to commit a crime it is an affirmative defense that, under circumstances manifesting a voluntary and complete renunciation of the criminal purpose, the accused avoided the commission of the crime attempted by abandoning the criminal effort and, if mere abandonment was insufficient to accomplish avoidance, by taking further and affirmative steps which prevented the commission of the crime attempted.
(c) A renunciation is not “voluntary and complete” within the meaning of this section if it is motivated in whole or in part by:
(1) A belief that circumstances exist which increase the probability of detection or apprehension of the accused or another participant in the criminal enterprise, or which render more difficult the accomplishment of the criminal purpose; or
(2) A decision to postpone the criminal conduct until another time or to transfer the criminal effort to another victim or another but similar objective.
