Apologies, when I was writing the post, I meant it as Barb's hoard played a hand in his death by exacerbating his already poor health. That was just kind of my knee jerk reaction because it's hard for me to not to get so angry at Barb knowing what she has done. I hade written a bit about Bob and how he was more relatable, but I deleted it thinking that I was going off a tangent.
Bob, for all his faults, did seem like he was trying to help Chris in his childhood. Perhaps it was a subconscious desire to compensate for neglecting Chris during his infancy and early childhood. He did try to stick up for Chris, even if his understanding of the events were based on Chris's incomplete/skewed accounts. At the very least, his approach didn't involve trying to run over whoever wronged Chris with his car. Bob even expressed alarm when trolls lead him to believe that his son was trying to commit suicide. Whereas if Chris's accounts are anything to go by, Barb would threaten to kill Chris when he became a tomgirl (Ok, Bob probably didn't like that either, but still). Bob didn't have to stay with Barb and Chris, he could've left them like he did with Patricia, David, and Carol. The fact that he devoted the end of his life to caring for someone as selfish as Chris and living with a woman like Barb speaks volumes about our favorite lumberjack. Bob's delusions I think can be attributed more to his old age as opposed to Barb, who we know has a history of being a terrible person.
