Deeds are evil, people are not. People's hearts are full of wickedness, and when it comes out, the person is defiled. Yet no one is beyond redemption. Righteous anger is not righteous, its judgememt. Only God and Christ have the right to judge, and so will we after Christ appoints us to that position and only after our hearts are clensed. Until then judgement of others leads to condemnation of the self.
