Kael is a very sarcastic person, his involvement with the dark arts has developed his morbid satisfaction for watching others suffer physically, and it carries over into emotional and mental anguish as well. He hardly ever laughs unless something malefic is happening and then, only a thin smile and a small chuckle might escape his lips. Despite his lack of sympathy for most living things, and his enjoyment out of manipulating his demonic minions, Kael hates the real demon threat and everything the burning legion stands for. He knows well enough about rules and politics to play along as long as they are in line with his agenda. And although he may be civil with the Horde at times, he gets his most enjoyment out of torturing them.
