In this excerpt from John Milton's Paradise Lost, Satan's likely motive for wanting to punish Adam and Eve can be inferred as follows:
A. He envied the love they shared, which he would never experience.
Explanation:
1. The excerpt portrays Adam and Eve enjoying bliss and love in Eden, which Satan, being cast into Hell, cannot partake in.
2. Satan's torment and unfulfilled desires are evident in the lines describing his pain and longing while witnessing the happiness of Adam and Eve.
3. This indicates that Satan may be envious of the love and joy that Adam and Eve share, contributing to his motive to harm them out of jealousy and a sense of deprivation.
Therefore, option A, "He envied the love they shared, which he would never experience," aligns with Satan's likely motive based on the given excerpt.
