As the old dragon above said (Kiya) it is said in the game that the soldiers do not want to be in Citadel. They are forced to join in and they are forced to torture prisoners. When I got into a room I saw a soldier who was afraid to go out. After finished talking to me he was shivering like crazy. Simply could not kill him. Nor the Imps. They are so sweet and kind! There are Battlefields for me to gain xp. And I always can slaughter Death Knights... This is a great joy indeed.
