Cane and Able were at odds with each other, but were still brothers. Family can be lost and become estranged. There are people on this very board who haven't spoken to mothers, fathers, siblings, cousins, and even their own children in years. Despite that, they are still family regardless of the state of the relationship.
Herman Cane was a brother. Lost, used as a tool, manipulated, foolhearted.......but still a brother.
Cain wasn't able to beat this Abel down...
...too soon?
