Littlefinger is the only person I see who would have the brains to run the throne.Who would you guys like to see take the Iron Throne? (if it could be absolutely anyone).
He liked Robb and he loved his brother. He only killed them because they were contending for the throne, which is rightfully his. Stannis was never fond of doing the things he did, but he knew he had to. Davos is a prime example of his justice.
And don't forget he also took a hiatus to defend the Wall while he was in the middle of a war. This man represents the integrity of a leader looking after his kingdom.
Madness.
Stannis only went to the wall in hopes it would gain him favor with the north.
He is a hollow husk of a man and a kinslayer, there is nothing honorable about him.
