The cutscenes aren't "interpreted" by Sly. That argument would make sense if we had several points of view on a single event and they were different. We have no reason to assume that the cutscenes are skewed by Sly's state of mind.

Also, Jim McSweeney does say that Conner was a good guy on page 9 of The Adventures of Sly Cooper, issue 2. "Your pop was a good man... We were pretty close." He also says "...he was one of a kind, that old man of yours." (And yes, the comics absolutely without a doubt are canon, so any arguments against them are invalid.)

McSweeney and Conner definitely felt like family. Why else would Conner allow McSweeney into his house and allow him to bounce Sly on his knee?
