Jedah Dohma was always distressed about the future of Makai (Japanese for "demon world"). He believed that if Makai was left under Belial's rule, the master of the Aensland family and the true ruler of Makai, then it would grow old and begin to decay. Belial would most likely say that such is destiny and life. Jedah considered Belial to be an abomination, and actively sought out the opportunity to kill him, waiting for the right time to strike.
