Why did Jon lock Ghost up?

[TheThreeEyedCow]

Gah, I was really enjoying this thread until the posters with an obvious bias showed up. 

I think the reasons for 'locking up' Ghost have been covered. Jon's being cautious with his new alliance with the Wildlings. And doesn't really need a giant direwolf beside him to be an effective administrator. Especially if it's threatening to attack someone or something. And Ghost really was misbehaving. It's clearly not similar to a dog that can be leashed. I think, similar to Dany, he;s in a bit of a pickle when it comes to the matter of his oversized companion. 

I just don't know if he's truly cut-out to be an administrator. With his warging, and his wolf and his strange berserker mode, I wonder if he's supposed to be a different sort of leader?
