Final answer:
Satan is jealous and resentful towards humankind, the new creations of God in 'Paradise Lost', and aims to corrupt them out of spite towards God.
Step-by-step explanation:
In Paradise Lost, Satan harbors feelings of jealousy and hatred towards God's new creatures, humankind. Satan, once an angel himself, has been cast out of Heaven and views the creation of man as an affront to his stature and a painful reminder of what he once was. The new creatures are seen as usurpers of the love and attention that he feels should rightfully be his as one of God's formerly most high angels. Therefore, Satan feels contemptuous towards mankind and seeks to corrupt them as a means of revenge against God. His feelings are complex, encompassing a spectrum that includes resentment, disdain, and a desire to subvert what God has deemed good.
