As a person moves up the ladder of spiritual awareness, his or her evil inclination is no longer down at the level of coarse lust and animal-urge temptation. People on high levels of emuna and observance of Torah rise to a level where their evil inclination is a holy angel. On a very high level, we find lofty type of angel that fought with Jacob. A similar angel pounced on King David, in the episode of BatSheva.
