And there's another story arc possibility. A protagonist who has some character flaw which affects their ability to be an effective adventurer has a development journey in which they confront and get over their flaw.
Or you can invert it, and have a hero develop a character flaw through their adventures. In some ways this is even easier. Just look at young Indiana Jones in The Last Crusade and his encounter with snakes.

The end of pacifism.
Knowing absolutely nothing about how this plays out in the movie, I'm willing to bet that Cassian is a major killing machine in the original.
Jim, err Jyn, his/her line in panel four makes so much sense that Cassian is properly speechless.
(I love the fortuitousness of the name match here, just like Annie/Anakin. You don't suppose somebody at Disney reads this, and deliberately decided to make that casting name? I don't suppose the sequel trilogy has someone named either Peter, Paté, Sally, or something similar?)
(Actually, Pete has to keep playing R2, so that's out, unless there's some strange, oddball, one-off movie... which there is, isn't there?)
Cassian: Well I'm glad I got here in time to kill Krennic.
Jyn: You killed him? Aren't you a pacifist?
Cassian: Back on the Ring of Kafrene, I thought I'd killed Wedge to save myself. It weighed on my conscience.
Cassian: I vowed never to kill again.
Jyn: But Wedge survived!
Cassian: Yes, learning that undermined my vow. But not killing was so addictive I just kept doing it.
Jyn: You killed that trooper in the data tower just now.
Cassian: By mistake. But—
Jyn: Yeah, even when you try not to kill people sometimes you kill them anyway. So what's the point? I understand now.
Cassian: Something like that.
