• The narrator uses the Invisible Man to experiment with the depth to which a person can sink when there are no social restrictions to suppress his behavior.

• Griffin begins his road to decline in college when he becomes so obsessed with his experiments that he hides his work lest anyone else should receive credit.

• When he runs out of money, he kills his own father.

• He excuses it away by saying that the man was a “sentimental fool.”

• When he takes the potion himself, he endures such pain that he “understands” why the cat howled so much in the process of becoming invisible.

• Nevertheless he has no compassion for the cat, for his father or for any of the people he takes advantage of in the course of trying to survive invisibility.

• On the contrary, he descends from committing atrocities because they are necessary to his survival to committing them simply because he enjoys doing so.

• Griffin at no time expresses any remorse for his behavior or for the crimes, which he merely describes as “necessary.”
