Well, consider this: You are probably aware that the word satan (Strong's 7854) means, adversary. That describes the Devil's primary role. However, the first two times the word satan is used, it does not describe the Devil, but rather God, who calls Himself an adversary of the wicked (Numbers 22:22, 32). And so, even if the word azazel is a proper noun, more biblical support is required before we conclude that it is the name of a demon.
