"John's favourite was Sam.", "No, John's favourite was Dean.", "John's favourite was actually Adam!"
John's favourite was actually the ghost of Mary Winchester that haunted his psyche to the point he neglected the shit out of all three of his children.
that man was consumed with grief and revenge and guilt because as dean says in season 5 “their marriage wasn’t perfect until after she died.” he was filled with regret and despair and while i do believe he did try, he neglected all of his kids as a result.
