Faintly evil. You can tell using either a detect evil spell or just good old racism.

The man chairing the Succession and Inheritance Committee is Evil, strong enough to faintly detect, and not making any effort to hide it. He was sitting with the elected delegates yesterday, but he's dressed like a nobleman.

A third person dressed well enough to be a noble heads over to the elected seats. This one's not evil! And wearing an Arodenite holy symbol around his neck. He's probably lawful neutral and really out of touch.

What the fuck. Even she knows that Aroden is dead.

The very pale noble girl who is rumored to have some connection to the undead isn't evil!

Neither is the kid in the committee with her, barely old enough to be here!

... Or the overt Hellknight, apparently.

The other Hellknight is very faintly evil, though.

The big swaggering Molthuni duke is evil.

Of course Aspexia del Mar isn't Evil, she's on the anti-diabolism committee! 

...Maybe the lady Hellknight just isn't a very powerful Hellknight?

The good-looking paladin in mithril chain with a holy symbol of Iomedae around his neck and on his weapons is not evil! Possibly because he's a paladin!

Eulàlia doesn't detect Evil! She assumes if she were strong enough to she'd have been put to death with her father. But she's a second-circle wizard and so there was nothing to see but a polite young woman whose thoughts were hymns to Iomedae through the whole execution. 

Carlota doesn't detect Evil and is mildly outraged that you wondered.

Nope. This strange elf with leaf tattoos on her face doesn’t detect Evil.

(If someone tried her a couple decades ago, that would be another story.)

Iomedae would never choose an Evil person to represent Her (and Cheliax should follow Her example in this).

What, really, was there ever any doubt?

Her spell says the Sarenrite's not evil, though the aforementioned Sarenrite disagrees with this statement.

The Archduke who proposed necromancy as a legal punishment (if she picked that up) is not evil, in spite of that.

This angry sortition delegate is not visibly Evil. (Almost none of the sortition delegates are.)

Neither is this one.

She's a hit dice short of being strong enough to detect as evil.

She's not, but fortunately she's also not evil!

He's not evil at the moment, but try again in a year and maybe you'll get a different response!

The learned Barrister possesses a Faint Evil Aura. What did you expect?

The count of Gualter has no aura.  Might be more a matter of lack of strength than lack of Evil, though.
