No, Luther just did not realize Glenn was a Cambion. Clerics are resistant to demonic surges/powers/stuff, due to they being (un)holy. Also, Luther is a rather brave man, he's not a citizen, but a merchant-fighter, who spent his life practicing the art of the sword. Evil-stares would work on most citizens and normal people though. For example, if Glenn tried to scare ordinary people, it would work, but if he tried to frighten a Gothic war cleric for example, it would not work.
As for the ladies, men tend to be scared of scary women, hence why female villains are so common in horror movies!
