Because he's finally growing a more human side to him and that the bigger bad is his father, Mac, who is deep down a violent, erratic and abusive man who abused James his whole life. James is becoming more of a tragic anti-villain now, which is why I added those sympathetic categories to his page.
But Mac made James into the man that he is now. Also, Mac violently beat up poor Jesse and almost hurt Neeta, even threatening her at their wedding. And who knows, he might have abused his other kids, Nathan, Ellie, and/or Alfie, and made them keep their mouths shut about it. Mac is becoming very unlikable, and you are vouching for him? Are you mentally ill or something?
