Which one wins, assuming the person with Den of Iniquity also has the highest honor? Can a player use Den of Iniquity to effectively negate Empty Victory (for himself)?

Until your Events Phase two turns from now begins, after an Action Phase ends, if the active player has one of the two highest Family Honor totals or is tied for the highest, he must declare an attack and choose another such player as the Defender, assigning at least one unit, if legal.
Political Limited: Bow this card and target another player's dishonorable Personality: His controller loses Honor equal to his base Personal Honor, or 3, whichever is lower. You may not declare an attack this turn.
