(a) No person, purposely or knowingly, and when purpose or knowledge is sufficient culpability for the commission of an offense under this General Offenses Code, shall engage in conduct which, if successful, would constitute or result in the offense.
(b) It is no defense to a charge under this section that, in retrospect, commission of the offense which was the object of the attempt was either factually or legally impossible under the attendant circumstances, if that offense could have been committed had the attendant circumstances been as the actor believed them to be.
(c) No person who is convicted of committing a specific offense, of complicity in the commission of an offense, or of conspiracy to commit an offense, shall be convicted of an attempt to commit the same offense in violation of this section.
(d) It is an affirmative defense to a charge under this section that the actor abandoned his or her effort to commit the offense or otherwise prevented its commission, under circumstances manifesting a complete and voluntary renunciation of his or her criminal purpose.
(e) Whoever violates this section is guilty of an attempt to commit an offense, an offense of the next lesser degree than the offense attempted. In the case of an attempt to commit an offense not specifically classified, an attempt is a misdemeanor of the first degree if the offense attempted is a felony, and a misdemeanor of the fourth degree if the offense attempted is a misdemeanor. An attempt to commit a minor misdemeanor, or to engage in conspiracy, is not an offense under this section.
