How do gta v s protagonists change throughout the story?

The verified evidence discusses the development history of Grand Theft Auto V, including its release timeline, development team size, and production details. However, it does not include any narrative or character development information about the game's protagonists—Michael De Santa, Franklin Clinton, and Trevor Philips. Without source material detailing their story arcs, relationships, or personal transformations, I cannot provide an analysis of their character evolution. The evidence focuses solely on production aspects rather than narrative content.
