Minos tells Icarus that the plan is dangerous because he wants to instill a sense of fear and caution regarding the flight. The plan itself is dangerous since it involves escaping with wings made by Daedalus where feathers were attached using wax, which could melt, leading to a fall. Despite the danger, Minos wants them to take the risk because Daedalus and Icarus are seen as threats, and escaping the labyrinth is the only way out of their imprisonment. Minos recognizes that Daedalus's skills and cunning could be dangerous to his rule, so their escape plan is risky but necessary for freedom.
