there was no character named Dan specifically associated with Emmerdale who had made a life-changing decision surrounded by guilt. However, please keep in mind that soap operas, like Emmerdale, are constantly evolving, and new storylines and characters may have emerged since then.
If there is a new character named Dan who has been haunted by guilt over his actions leading up to a life-changing decision in Emmerdale after 2023, I would not have that information. To get the most accurate and up-to-date information, I recommend checking the latest episodes or official sources related to Emmerdale.
