Well I've never read anything quite like it. I enjoyed the story and the writing. I think it was memorable and nuanced, and gave me enough to ponder and think about deeply. Didn't appreciate the offensive language, but it wasn't more than pg13. 
 I've been thinking about some questions that I think the author asks us to ponder as we read the story and begin to sympathize with one brother and not the other. Three of them that I've thought of are 'when someone is involved in heinous crimes does it matter if they have redeemable characteristics?' and perhaps 'what justifications do we come up with in our own lives to feel fine about our actions' and maybe also 'Is there a point where we are un-redeemable because of our previous actions even if we renounce such actions.'
