Osang, a married woman in her early twenties, was sleeping on a banig on the floor of their nipa hut beside the seashore when she was awakened by the act of a man mounting her. Thinking that it was her husband, Gardo, who had returned from fishing in the sea, Osang continued her sleep but allowed the man, who was actually their neighbor, Julio, to have sexual intercourse with her. After Julio satisfied himself, he said "Salamat Osang" as he turned to leave. Only then did Osang realize that the man was not her husband. Enraged, Osang grabbed a balisong from the wall and stabbed Julio to death. When tried for homicide, Osang claimed defense of honor. Should the claim be sustained? Why? (2000, 1998 BAR)
