Aldecain was cruel and had a bad temper.
Aldecain held Moiraine's father in contempt because he was a scholar and he married another scholar after the death of his first wife. Aldecain believed that he should have married a noblewoman to increase the prestige and fortune of House Damodred. Moiraine disliked him because of this and felt no sadness upon being informed of his death.
