Exploring Batman's Discipline: Why Comics Miss His Psychological Development?

Batman is often portrayed as a paragon of discipline and willpower, qualities that define his character as much as his physical abilities. Despite this, it seems rare to find comic book narratives that deeply explore the psychological aspects of how he developed these traits. While ‘Batman Begins’ touches on his early days and training, it’s surprising that there aren’t more detailed stories focused on this aspect of his journey. Why do you think the comics have largely overlooked this part of Batman’s development? Are there any lesser-known comics or materials that delve into how Batman honed his exceptional discipline and willpower?
