Keith was unaware of the emotional turmoil that the Demon God part-timer had when he used the Eyes of Heaven to see through his secrets.
To be honest, Keith didn't care about what the Demon God felt. In his mind, he was already plotting against the Demon God as he planned to make use of his identity as the owner of McDowell's to make the Demon God his subordinate.
Keith was confident that as long as the Demon God was on planet earth, he could never escape his grasp even if the Demon God went to North Korea. After all, North Korea wasn't part of the Unified World Alliance under Keith's banner but it didn't mean that it wasn't under surveillance.
