[Witcher] If Geralt decides to kill Whoreson Junior, Dudu later assumes his identity and uses his wealth to start a legitimate enterprise. Why is Dudu not overcome with Whoreson Junior's sadistic urges like when he shapeshifted into Caleb Menge?

Dudu explained that dopplers also assume the personality of the people they shapeshift into. He mentioned in the quest where Geralt frees Dandelion that he felt uncomfortable in Menge's form and was almost overcome with the desire to torture mages. Why didn't the same thing happen to him when he became Whoreson Junior even though he spent a much longer time as him?

Perhaps the willpower of the person affects how strongly their personality imposes on you? Whoreson enjoyed killing women and such, but Caleb's desire to torture mages came from a deep, dark, fanatical place. Dudu may be able to suppress and ignore Whoreson's urges (which Whoreson himself could have done, but couldn't be bothered to because he was a shithead), but Caleb's insanity ran too deep to suppress.
