A character's personal journey through a story is known as a character arc. The arc frequently features an inward transformation that is mirrored by an exterior transformation. There are four different sorts of character arcs that are well-known to authors including moral ascending arc, moral descending arc, transformational arc, and finally, flat arc.

Whatever character arc the writers decide on will be crucial to moving the plot along to show how the characters are affected as the action takes place. After the story's conclusion, some characters get better while others get worse which is known as a moral descending arc. These are some major TV and movie characters who enter the story as good guys but walk out as bad.

Walter White - ‘Breaking Bad

Breaking Bad is a crime drama series that centers on Walter White (Bryan Cranston), an underpaid, overqualified, and underappreciated high school chemistry teacher who is coping with stage-three lung cancer. Thus, White turns to a life of crime and teams up with his former student, Jesse Pinkman (Aaron Paul), to manufacture and sell crystal meth.

As the show’s title suggests, it’s a tale of how White breaks bad, or more precisely, how he accepts and embraces his actual color. White's gradual descent into darkness progressed more each time he crossed a line further into impiety. In the beginning, it was evident that White chose to take on the Heisenberg persona consciously, but as the series progresses, the distinction between the two personalities blurred as White eventually transformed into his alter ego.

He possessed traits of a Sith and had to suppress his negative emotions for years to become a Jedi. Eventually, Anakin yielded to the dark force and accepted his evil side. Additionally, Anakin's inability to separate from those he cares about deeply is another weakness. As a result, he was estranged from the Jedi Order and was drawn closer to Palpatine and the Sith.

Saruman (Christopher Lee), also known as Saruman the White, was the first of the Istari (Wizards) and the commander of the White Council, which stood in opposition to Sauron.

Fans first met Saruman in Peter Jackson’s original trilogy as a complete slave to Sauron's will and his own drive for power. He was, however, still on the side of righteousness in the Lord of the Rings prequel, The Hobbit: Battle of the Five Armies the last time viewers encountered him. Thus, fans assume that Saruman was influenced and gradually corrupted during the confrontation with Sauron, which was never mentioned in any of the franchise material.
