MESSAGE RATING IMAGES

i was thinking about the images that are associated with orange soapstone messages. whilst i must admit theres a good chance the pics were chosen at random, but  could it be possible the character image associated could be related to how trustworthy the character is?
to clarify for anyone who doesn't know how it works, you can leave a message with the orange soapstone, (generally used to give advice, though often used to fool other players) and by pressing a button (select i think?) you can rate the message, positive or negative. enough positive votes and the little picture that accompanies the message will change. the images are as follows-

1. Undead
2. Knight Solaire
3. Lady of Darkmoon
4. Domhnall of Zena
5. Frampt the Primordial Serpent

i took the list directly from one of the wiki sites and would like to state that the "undead" is clearly the undead merchant (could be either male or female one) and its not certain whether the serpent is Frampt or Kaathe.

now, my theory is that the higher rated the message is, the more trustworthy the advice, and as such relates to the character image.
-the undead merchants are dubious and only really interested in themselves and making profit. not terribly trustworthy
-solaire is a nice guy, but a little insane and doesn't really know where he's going in the land of lordran. just that he's looking for his sun (whatever that may be)
-lady darkmoon, trustworthy to a degree, but tight-lipped. seems to be withholding information.
-domhnall, like the merchants, is more interested in trade, BUT will dole out some invaluable (and accurate) information regarding certain areas of the game.

-serpent- these characters give you the most direct information on your purpose. of course the information one gives contradicts the other to a degree, so which serpent does the image relate to? either i suppose. the one you believe to be the truth. (and as such is a nifty little joke on the part of from software, if the trust theory is correct)
