Arahants are perfect. Do they realize others are not perfect and they themselves are?

Arahants have eliminated the conceit of, "better," amongst other aspects of conceit and other fetters. However, if they are perfected people, that would mean they are perfect. Other people are not perfect, by very virtue of not being arahants. How do we explain the fact that an arahant doesn't feel better than anyone, though in reality they are better, morally, spiritually, and emotionally? Doesn't an arahant also lack ignorance? It seems knowing what you are and where you stand is a lack of ignorance.
