Evenly and openly, Lord Mhoram said, “I have no special virtue to make me resent him. One must have strength in order to judge the weakness of others. I am not so mighty.”
(This is regarding Mhoram's lenient attitude toward Covenant). And yet Mhoram judges Lord Foul, most severly - hypocrite much.
If Mhoram and the rest had taken an 'Oath of Justice," instead of an Oath of Peace, they might think differently about the rapist within their ranks.
