Here the plot takes a turn that's completely different from Paradise Lost: in both GL and GC, Satan doesn't decide to go and destroy the righteous humankind on his own, even preventing the other devils from doing so, but he sends the hellish army. The role of the Tempter will anyway be soon played by the beautiful Lilith-like witch Armida, whose intervention in the war will in fact be 'suggested' by the devils. Later on in GC (not in GL), a huge and powerful devil called "Fortune," a mix of Satan and Poseidon, will take part in the battle of Jaffa.
Quite interesting is the psychological characterization of Satan in these lines. He asks the devils to spread everywhere the very fire he feels burning inside himself, but at the same time he doesn't want that fire to go out.
