I do agree that PP is a bit of a sociopath and I remember someone once telling me that Disney actually hated the character because he found him creepy.
That was me, actually. It was a bit of trivia I found some time ago in Pan’s page from Disney Wikia:
Even though his film was a success, Peter Pan was not one of Walt Disney’s favorite characters because he felt Pan was too immature and cold. This is less prevalent in the Disney parks, however, to enable better interaction between park guests and fellow characters, but he still does not like to be kissed by girls most of the time.

IIRC, I brought that tidbit to the forums a week or so after season 2 ended. Back then there were people in denial that Peter was going to be a villain and were trying to find loopholes, to which I countered that for all his heroic portrayals in media Pan’s personality curiously seemed to be defined by far more negative traits than positive ones, citing Wikipedia and the article above as sources.
Of course, not even I imagined back then that A&E would go this far with making a villain out of PP. This Peter seems completely irredemable to me and death does look like to be the only logical conclusion to his story, which saddens me as I was kinda hoping to see, for once, a Peter that ends up with Wendy. Sigh, so much for that! 🙁
