Heres what I mean so read carefully,
The mother Maureen Mcreary loves all her kids since she is the mom (She lets the killing gangster children packie and gerald live with them). But what about the brothers? For example They all say they hate Francis, but what if they all love eachother because their family
however their differences and hate for eachother outweighs the love.
like Francis could love derrick, but his selfishness and hypocritical personality still makes him willing to have derrick killed. I mean francis doesn't seem to let the cops really bring his brothers down so...
also do all the brothers most likely love kate?
or perhaps its as simple as they all hate eachother with no love,
your thoughts based off this argument.
