Personally I love all of them. Alois is my favorite. I like his character and I personally just feel sorry for him. I guess I sort of see him as the sort of "Harley Quinn" of the game. If you get the reference.
Like Harley Quinn, Alois wants to be with the one he loves but like the Joker, Justine uses his emotions to get what she wants and screws with his head. You think he would leave but he doesn't and I feel bad for him because of him.
Poor man just wanted to be loved.
