Balthazar

Balthazar was a human Bhaalspawn and the last of the five. He was probably the most powerful of them and was the only one who did not want the power of Bhaal to cause chaos. Before his death he was the ruler of Amkethran. He wanted to destroy the power of bhaal forever and felt the only way of doing this was to first enhance the Bhaal's power and then kill himself, hoping Bhaal will die too.
