In what way wasn't she a typical Vorta?
For them the Founders are gods, Founder ideology is that you cannot trust Solids (unless they consider you as gods
) and in a theocracy the worst crime is to doubt the word of your god(s).
She was as evil and stupid as any other Vorta ... although you could of course claim that they follow a 'suck up to the boss' strategy, that their belief is fake and a way to gain power in the Dominion. So yeah, perhaps they are evil and smart.
