i don't necessarily think will is a good parent, but i don't think he's a bad one either. he's more just like an adult who is in charge of a child- one who can care for them and provide for them, but not exactly hold all the natural sense of paternity or love for that child. any love he felt for abigail was just garrot's love for her. his attachment to walter is very superficial, and there aren't any scenes given that indicate will actually feels anything... loving towards the boy. he takes care of molly and walter for sure- plays the role really well of provider, husband, and step-father. but he "plays" them. he's not really feeling any of it. i think will really wants to feel it, to have that kind of sure, emotional and loving attachment to a child like a parent should, but in the end, they aren't *his* kids and they come secondary to whatever attachment he had to the adult that was around him first. so, even though i think will certainly attempts to fulfill the role of good parent, it falls flat because he is merely playing at the role and isn't invested in it
