“My Brothers Keeper” is a flippant remark made to the face of God by a Murderer.
Cain, when asked by God, “where is your brother Abel?” said, “Am I my brother’s keeper?” This, after he had just Murdered Abel.
I think it is absolutely fitting that scumsuckers like Holder and Obama take this as their motto. They are merely reminding anyone who pays attention of their godless and lawless behavior.
