It might be the Stormfather, but he might change depending on the person hes "anchored" too. Him considering attachment to Gavalar might have made him more cynical and scheming. Then again just listening to G's surface thoughts would have made anyone feel the need to watch themselves around that kind of manipulator, But when he considered then bonded Dalinar he would have seen pain and guilt and regret, but not the same level of calculated malice and willing to sacrifice and destroy for power.
Just a thought.
