"Am I my brother's keeper" most famously quoted from the movie New Jack City, meant do I have my brother's back or not? Unfortunately for the brothers in that movie, killing them meant he was keeping them from "jacking up" the business anymore than they had. Being your brother's keeper should mean I have your best interest at heart and I will not let anything happen to you.
