As the father of 4, I find myself to be both the hero and the villain.
I think I'm the hero most of the time, pilgrim !
I'm the damsel in distress! Lol!
Hero and villain are such limiting terms. I'm the stumblebum who keeps tripping over his own feet. I guess that makes me the clown of my story.
I'm the Master Jedi Knight in any story and the Force is with me ;)
I'm the plucky, wise-cracking sidekick.
Hero and Villain denotes Good and Evil in most ideologies.
Since I do not subscribe to Evil or Good as things governed by outside forces . . . I would be "The Guy who tries to do the best ethical thing based on the circumstance" in my story.
I am the Lord of the Locker. I am not a hero. I am a villain in my story. My story is exactly the same as your story just one chapter behind.
Only my daughter sees me as having that much power. (Once the electricity went out in our entire city, and she told me I ruined everything!) But in truth, I usually play more of a supportive role in life's drama.
Would the villain think of him/herself as the "villain"? Not normally. They believe they are the "hero" ... Working to make the world a better place, as they see it.
I'm always the a**, I don't try to be but I'm great at screwing everything up.
Usually the villain but mostly the hero.
