This is most clearly seen in the film's central conflict, in which Jessep orders the "Code Red" hazing of a young Marine, ultimately leading to the man's death.
Despite his flaws, Jessep is also a highly intelligent and cunning character, and is able to manipulate the legal proceedings against him to his advantage.

In the end, Jessep's flaws and mistakes catch up to him, and he is forced to confront the consequences of his actions. However, even as he is found guilty and sentenced to prison, Jessep remains unrepentant and defiant, declaring that he would do it all again in order to protect the Marines under his command.
Overall, Nathan Jessep is a complex and well-developed character, and his role in the film "A Few Good Men" is a crucial one. He serves as a foil for the film's protagonist, Lieutenant Kaffee, and his actions and motivations help to drive the plot and explore the film's themes of loyalty, justice, and the cost of upholding one's beliefs.
