In this section a debate is had and satan decides that instead of a war with heaven again they are to visit earth or more specifically eden and mess with it. Satan decides he’ll go before anyone else wants to. In book 3 god sees satan after eden and gods son says mankind will fall to satan.
Later god goes to tell of satan successfully tempting mankind and that he will punish all of them because they go against his will. Even though its all part of his plan to have it happen.
