The Glass Castle
"Living with an alcoholic is a family affair. Because it subjects all members of a household to constant stress and fears of various kinds, it has often been referred to as a “family illness.” To one degree or another, all members of the family are affected." All the family members in the walls family were affected by Rex's actions. Everyone suffered and it made their family break apart to the were there can be no repare. I dont think anyone would ever admit that when he died there was a sense of release.
