(1) No one shall be punished under § 30 if he voluntarily:
1. abandons the attempt to incite another to commit a felony
and who averts the possibly existing risk that the other person
will commit the crime,
2. after having declared his willingness to commit a felony,
gives up the idea or,
3. after having agreed with others or having accepted the offer
of another to commit a felony, prevents it.
(2) If, quite apart from anything done by the abandoning party,
the crime is not committed, or if it was committed independently
of his antecedent conduct, no punishment shall be imposed on him
if he voluntarily and earnestly endeavored to prevent it.
