"Now, the adultery of the woman is a very serious attack on the honor and dignity of the man," the ruling, signed by Judge Joaquim Neto de Moura, said. "It was the disloyalty and the sexual immorality of the plaintiff that made (the defendant) fall into a profound depression, and it was in this depressive state and clouded by the revolt that carried out the act of aggression, as was well considered in the judgment under appeal."
"This case is far from having the seriousness that, generally, is presented in cases of mistreatment in the context of domestic violence," the ruling says. "On the other hand, the conduct of the defendant took place in a context of adultery practiced by the plaintiff."In addition to that, the court also cited a 19th century Portuguese law which recommended only symbolic penalties if a man kills his adulterous wife.
In conclusion, because the nation is European and predominantly Christian and the religious text cited is the Bible, we'll never hear about this case again.
