Griffin's behaviour throughout the story reveals him to be both a brilliant but deeply lawless and irresponsible person.
Misuse of science: Griffin discovered how to make the human body transparent — a remarkable scientific achievement. However, instead of using it for the benefit of humanity, he used his invisibility for selfish and criminal purposes.
Acts of lawlessness:
Conclusion: Griffin's genius is beyond doubt, but his misuse of his discovery for revenge, theft, and violence makes him a danger to society rather than a contributor to it.

The examiner expects you to address both aspects implied by the question: Griffin as a scientist (brilliant, pioneering) and as a person (lawless, irresponsible). Cite specific incidents from the text — setting fire to the house, theft from the store, robbing the shopkeeper, burgling the clergyman — rather than making vague claims. The concluding line balancing his genius against his criminality earns full marks. Aim for 6 concrete, text-based points for a 6-mark answer.
