How to write a redemption arc

Flawed

Start with a flaw that they must overcome.

EXAMPLE

Jake's anger leads him to make a costly mistake. This hurts those he loves.

Seeds of Change

Show early signs that they may overcome their flaws.

EXAMPLE

Jake quietly stares at an old photo, his eyes betraying a flicker of regret.

Rock Bottom

Show them at their lowest point.

EXAMPLE

After a reckless outburst costs him his last friend, Jake realizes his anger has left him utterly alone.

Realization

Let them acknowledge their flaw and the damage it's caused.

EXAMPLE

Seeing his reflection in a shattered mirror, Jake confronts who he's become.

Forgiveness

Show them wanting forgiveness.

EXAMPLE

Jake visits those he's wronged and apologizes.

Challenges

Show how there are many challenges to them changing -- temptation, backsliding, etc.

EXAMPLE

Despite his efforts, no one forgives Jake.

Support

Add a character who sees potential in them and tries to help.

EXAMPLE

A former rival, noticing Jake's genuine effort, starts helping.

New Identity

Let them develop a new, better identity.

EXAMPLE

Jake volunteers at the homeless shelter to make amends for the damage he caused with anger.

Final Test

Add a situation that would have previously set them off. Let them make the right choice.

EXAMPLE

Jake's boss yells at him over a simple mistake and fires him. Jake takes a deep breath and chooses not to be angry.

Acceptance

Let others gradually accept their change. This should feel earned.

EXAMPLE

At a community gathering, Jake's ex-friend nods at him. People also accept him at the community gathering, whereas he would have been shunned previously.

Continued Growth

Show that redemption is a continuous process and not a destination.

EXAMPLE

Jake mentors a troubled youth on how to not give in to anger.
