I don't know about DmC because Donte is a character with bunch of inconsistent personalities, but in DMC3, he denies his demon legacy and his father's role but later he starts to acknowledge it after lady started explaining what family is to her, and after realizing what his father did by sealing the hell gate.
Dante expresses no malice towards Sparda in DmC. He doesn't even remember who his father is during those initial few missions.
Dante in DMC3 is bitter over the attack on his family when he was a child. Sparda is indirectly responsible for it, and, for whatever reason (He was dead?), he didn't protect them. --- ~@_@~ Why are you people so hung up on what's canon or not? - freakazaa
