When we look at the poem in book 1 lines (50-51-52-53) we can see he talks about, sending Satan to Hell.
"Nine times the space that measures day and night to mortal men, he with his horrid crew lay vanquished, rolling in the fiery gulf confounded though immortal"
In this paragraph Milton tells first fall to Hell of Satan. He says, Satan and Fallen Angles Lays in the Hell nine days and nine nights as an effect of fall. Their minds confuse but they didn't lose their immortality and their hate is still continuing, although they are in the Hell. In this paragraph we can see sending to Hell all the Fallen Angles are shown us as a punishment, so it is expected to Fallen Angles and Satan to be sorry, but they never lose their hate.
All the fallen Angles lost their name after they had fallen to Hell. If we look lines (84-85-86-87) we can see here Satan's first talk and he is thinking about things that he lost after he had been driven away.
"If thou beest he - but O how fallen! How changed from him who in the happy realms of light clothed with transcendent brightness didst outshine myriads, though bright!"
Satan also talks about his rebellion against God and he talks about himself right and proud. Satan says I won't change against to power of God. According to Saran, he is right but God isn't because God used force to him. When we look Milton's representing of Satan we can clearly see that he is talking about Satan as a proud, right and honourable.
"That durst dislike his reign, and me preferring, his utmost power with adverse power opposed in dubious battle on the plains of Heaven, and shook his throne. What though the field be lost? All is not lost:"
In this paragraph there is an image of Heaven's Garden and in this garden God and Satan are fighting. In book 1 lines, (102-103-104-105-106). Satan says, we have not lost this war yet and we will continue to fight against him, and also he says I will not beg to him for forgiven. Again we see Satan is very proud and this time conceited.
"Is this the region, this the soil, the clime, said than the lost archangel, this the seat that we must change for Heaven? This mournful gloom for that celestial light?"
Book 1 lines (242-243-244-245). In here Satan asks, is this place that we will stay instead of Heaven? Than he answers however it would be worse I will appropriate here. There is also representing of God in this page. Milton represents the God, someone who proud things that he has done. Milton talking about him as a negative character.
"Better to reign in Hell than serve in Heaven"
In this paragraph Satan says, it is better to be a ruler in Hell than to be a server in Heaven. One more time Satan is represented as an innocent.
When we take a look at book 2 we see Fallen Angels here. They are saying their ideas to Satan and arguing. If we look book 2 lines (115-116-117-118-119-120-121-122-123-124). We see there is a Fallen Angle's talk (Belial).
"For his thoughts were low, to vice industrious, but to nobler deeds timorous and slothful: yet he pleased the ear, and with persuasive accent thus began: I should be much for open war, o peers, as not behind in hate, if what was urged main reason to persuade immediate war did not dissuade me most, and seem to cost ominous conjecture on the whole success".
