Allah, the Exalted, gave the angels intellect without desires, He gave the animals desires without intellect, and He gave both to humans. So a man whose intellect prevails over his desires is better than the Angels, whilst a man whose desires prevails over his intellect is worse than the animals. -Imam Ali (a.s)
