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.

The half-elven count is strong enough to have an aura, but it isn't Evil.

The other druid is not Evil and also believes she understands Good and Evil much better than the Chelish humans and their stupid spells! Or a goddess who isn't Good or Evil herself, for that matter! If you told her a spell said she was Evil she'd call the spell wrong.

The woman sitting among the religious delegates wearing Irori’s holy symbol detects as faintly evil!  If you bothered detecting law, you would also detect a stronger aura of law.

Not detectably evil.

No evil or any detectable alignment on this young man sitting among the nobility.  If he had just cast his healing spell you might get a false positive on detecting Good!  Or if you had a "detect celestial presence" to match your "detect fiendish presence" his bloodline might give a false positive!  Sadly neither of these are the case, so he will miss out on the opportunity to explain his illustrious heavenly bloodline!

Llei is faintly evil! This cannot possibly be surprising, but now you can tell yourself that you checked and didn't just assume.

This man in the elected's seating is not detectably evil.

Evil, and making no attempt to hide it.

None of the power Roger ĥas is the kind that makes you show up to detect spells.

Faintly Evil.

Evil and still strictly speaking worships Asmodeus and has made no attempt to hide either.

Not Evil.

Not evil, as he repeatedly claimed.

Evil, strong enough to ping, not hiding it, and on his way in giving his nephew a silver piece to go buy snacks.

First circle. Abadar provides an aura of Law but if there's also evil under there you can't tell with such rudimentary methods.

A cleric of Iomedae sporting five hit dice reads Strongly Lawful Good.

A cleric of Shelyn with somewhat fewer hit dice than that reads weakly Good.

Not evil.

Faintly evil.

A wizard who is somewhat shy of the border of leveling doesn't have a - maybe that's an aura? It - no it's gone again - it didn't look Good, at any rate.

As a cleric of a True Neutral god, Jofre will not ping until he has grown up big and strong, and that's only if he develops moral convictions other than "I want to go outside" or systemic ones other than "you can't operate a ship if there's outright mutiny on the table for anything that's not itself ridiculously lethal", which Pharasma doesn't seem to find important.

This important-looking noble isn't evil!

(Hahahaha no he's totally evil. He's just never won a fight against someone stronger than himself.)

This elf is definitely not evil. She left Cheliax before evil got popular.

Also not evil. She ran away from home, and then fought Cheliax, when it was good to do that!

Not evil!

Here’s a sortition delegate strong enough to detect as (faintly) evil.

Would have to be faking the whole "Desnan cleric" thing to be evil, and isn't!

It's almost like he's under the influence of powerful magic that makes him immune to all divinations. Are you checking? 

This guy could pass as a human with an unusually ashen complexion who's keeping his head down literally, but if you do realise he's a tiefling it's not ambiguous. He doesn't detect as Evil, though.

Neither evil nor strong enough to detect.
