Warring against people isn’t that easy for the demons. In the course of the battle, they feel sorrow and unease, particularly when faced by stronger opponents, that is the saints and perfect Christians. Otherwise we wouldn’t be talking about a battle between us and the demons, but about our rout and extermination. Since they’d totally wipe us out without effort or any danger to themselves. So there’s tension on both sides, then. For both sides, defeat’s painful and causes consternation, whereas victory brings joy. So if they sometimes get the better of us, it’s also possible for us to pay them back.
