Richard Cameron

"Hey, in case you haven't heard, Dalton. There's something called an honor code in this school, all right? If a teacher ask you a question, you tell the truth or you're expelled. (...) He's right there, Charlie. And if you guys are smart, you will do EXACTLY what I did and cooperate! They're not after us! We're the victims! Us and Neil."

- Richard Cameron's true colors and betrayal.

Richard Cameron is the supporting character turned antagonist in the 1989 film Dead Poets Society. He is a loyal obedient student of Welton Academy and originally a member of the Dead Poets Society group until his betrayal following the news of Neil Perry's suicide.

He is portrayed by Dylan Kussman.

History
A student of the prestigious Welton Academy for boys, Richard Cameron is an insecure guy who is afraid of getting in trouble, but decides to join the Dead Poets Society group because of his roommate Charlie "Nuwanda" Dalton.

Unlike his classmates, Cameron is skeptical for that he did not agree with the teachings of John Keating and echoes Headmaster Nolan’s criticism of Keating's unorthodox methods from the very beginning, even reluctant to tearing pages from a poetry book and asks whether he will be tested on the lesson about seizing the day.

He only followed along with Keating and the DPS members, since everyone else from his class did. While Cameron attends meetings of the Dead Poets Society, he does so very reluctantly, since he’s terrified of being caught and expelled from Welton.

After Neil Perry committed suicide as a result of his father forcing his son into military school after the play, Cameron plays an important yet betrayal role, that in his defense he blames Neil's death on Keating to escape punishment for his role in the Dead Poets Society, and reveals the club's secrets along with naming the other members to Mr. Nolan.

Dalton becomes enraged by Cameron's treachery and was expelled after he furiously punches his former friend. After Keating is fired from Welton, Cameron along his classmates are now under Mr. Nolan's teaching at English class for the time being, who then gave a complete poetry book to Cameron after realizing they have skipped over realism which most of it were teared off earlier from Keating's orders.

Unlike the DPS members, Cameron (along with the other non-DPS members) did not rebelled at the end of the film, but was surprise after seeing his former friends does so in loyal to their former teacher.

Trivia

 * Cameron being the only DPS member not to rebel against Mr. Nolan at the end was actor Dylan Kussman's idea. Originally, Cameron was supposed to stand on his desk in the final scene like the rest of the Society. However, Kussman felt that this would be out of character and said so to director Peter Weir. Weir agreed to Kussman's surprise, and so they changed it to Cameron remaining seated.
 * His betrayal is foreshadowed at the start of the film when Cameron is holding the "Tradition" banner, which signify his loyalty to the school and Mr. Nolan.
