In the Channel 5 documentary 'Prince Harry in Therapy,' royal experts discussed the Duke of Sussex's feelings of embarrassment regarding his pre-Meghan life, particularly his 'laddish' behavior during his time in the army. Author Tom Quinn highlighted that Harry, once known as the 'party prince,' would now be horrified by his past actions, including using a racial slur to describe a fellow soldier. Harry himself reflected on this in his memoir, 'Spare,' acknowledging his ignorance about unconscious bias and the implications of his words, which he attributed to his sheltered upbringing. Additionally, Harry has expressed regret over wearing a Nazi costume to a themed party, labeling it one of his 'biggest mistakes.' Experts opine that Harry's evolution is significantly influenced by his marriage to Meghan Markle, suggesting that he now views the world through a different lens, validating his previous feelings. His attempts to rectify past mistakes include meeting with a Holocaust survivor, demonstrating his commitment to understanding and addressing the impact of his past actions.
