The family was viewed as sacrosanct: divorce was highly unusual and children were expected to be grateful for the sacrifices that parents, who postponed their own gratifications in forming a family, made on their behalf.

Espionage is about redefining Good and Evil, the violable and the sacrosanct.

Origin:
Sacrosanct comes from Latin sacrosanctus, "consecrated with religious ceremonies, hence holy, sacred," from sacrum, "religious rite" (from sacer, "holy") + sanctus, "consecrated," from sancire, "to make sacred by a religious act."
