John Milton Paradise Lost Books 1, 2 & 12

Satan is often called a sympathetic character in Paradise Lost, despite being the source of all evil, and in the first chapter the reader is presented with some of Satan's frustration. Satan tells his army that they were tricked, that it wasn't until they were at battle that God showed the true extent of his almightiness. If they had been shown this force previously, not only would the rebel angels not have declared war on heaven, but Satan, also, would never have presumed that he himself was better than God. Satan comes across as an unrepentant rebel who is willing to fight an authority that he deems unfair. Many people find this attractive.
