Our reading
An editorial interpretation.
Affection and a hard limit arrive together here. The speaker affirms love for an older brother, then demands that the brother never again side with anyone against the Family. The closing 'Ever.' makes the line absolute, ranking loyalty to the Family above even the closeness of brotherhood.
