>>Woah, man. You need to read that passage again.<<
The Jews thought Jesus must be evil, since he could command demons. (If they obeyed him, he must be their leader, the prince of demons, they figured.) This reflects a dualistic contamination of the Jewish religion, which they picked up in exile in Babylon, Zoro territory. By answering "a house divided against itself cannot stand," Jesus was reaffirming monotheism: that demons can do nothing that God does not permit them to do.
