PERSONALITY:
Raised to be a soldier, Finn is inexperienced to the world outside of the First Order, and knew nothing else but to be dutiful to his officers and trust in the First Order's goals. Compared to most Stormtroopers, he is still protective, intelligent, and strong enough that at one point he was considered to be one of the best Stormtroopers. Despite this regard, Finn is friendly and cared about his comrades enough to risk his own life for their safety. But Finn's loyalties changed when he witnessed his first field operation on Jakku watching the destruction and massacre of many innocent villagers by the First Order, including the death of a fellow Stormtrooper he had known personally. Seeing the true nature of his superiors caused Finn to start questioning who he was and wanted to abandon the life he had with the Order from this disillusion.
This decision, among most of his negative actions, stems from Finn's greatest shortcomings; the fear and stress that he had sustained from the First Order. These traits can lead him to sudden panic, deserting others out of cowardice, or refusal to keep fighting a conflict where he knows how dangerous the First Order can be.
However, Finn is good-natured and has a sense of justice, honor and empathy. Though he can be influenced by his past fear, Finn goes out of his way to rescue others who are less fortunate, including Poe Dameron and Rey when the two were captured by the First Order. When learning of the bravery of the Resistance in the face of the First Order's brutality along with the influence of his friends' altruism, Finn becomes more confident in himself and officially joins the Resistance to protect the Galaxy from the First Order.

TRAITS:
Kind, nice, brave, heroic, empathetic, good-hearted, dutiful, noble, well-meaning, selfless, fearful (formerly), timid (formerly)

QUOTES:
"The name's Finn, and I'm in charge now."
"We go back to Jakku, we die!"
"I'm not Resistance. I'm not a hero. I'm a stormtrooper. Like all of them, I was taken from a family I'll never know. And raised to do one thing. But my first battle, I made a choice. I wasn't gonna kill for them. So I ran. Right into you. And you looked at me like no one ever had. I was ashamed of what I was. But I'm done with the First Order."
