Well, greetings to the Shard.
Today I was suddenly struck by realisation so strong that I brought my thoughts about it here. A note: English is not my native language, therefore sometimes I probably will sound like Huio speaking Alethi; please forgive my occasional mistakes.
So, what's this all about? I looked on Divine Attributes, then looked on Heralds, and I saw this: most Heralds lost their so-called Primary Attribute, but kept their Secondary Attribute.
Nale is unjust and even psychopathic, but he's definitely very confident in his own motivations and actions (at least when there's no Lift, Szeth or Dalinar around).
I'm not sure about Shalash's creativity, but her obsession with destroying Heralds depicting art sounds to me like something opposite to creativity. However, she's very honest wuth herself and others about Heralds' - and her own - guilt and responsibility for their lie.
Kalak is not resolute in any way: we saw him in RoW as totally indecisive person, and he's getting worse. But he's still a builder - at least he built Sons of Honor IIRC.
Ishar is claiming godhood and making abominations, so, I think, he's not counting as pious. But is he guiding? Yes; we saw him guiding Nale and Kalak to killing potential Surgebinders, and he possibly led Heralds to betrayal of Oathpact.
If Taravangian is right, and Dova is really Battar in disguise, we see another example of madness: she cares about people and Desolations, but suggesting Death Rattles is not wise at all, rather quite opposite.
I'm still not for 100% on Chanarach Davar side, but if it's true...well, we see probably obedient, but not so brave woman.
About other Heralds I have doubts or no important information about their madness.
What do you think?
