Actually the pleasant disposition and fighting for good is what makes a Dark Knight a Dark Knight. You RESIST the evil inside you. Because if you do become fully evil, that's not a cliche, that means the Darkside wins and you cease to be.
It's like Naruto and Ninetails. If the Ninetails consumes Naruto he becomes a terrible beast that just wreaks havoc and he has no control of his own body. Or your Shadow in Persona 4 that if you don't accept it and learn to control it, it would consume you and you end up daed.
Dark Knights channel the darkness inside of them, Warriors struggle to control their Rage. They are similar in that they must not give in to the darker sides of them or they cease to be who they are.
Now you could role play the evil side of you that took control, but any semblance of who you used to be is consumed and is no longer available to be in control of your body since you would have fallen from grace too much to come back.
Imagine a dark voice whispering in your ear constantly tempting you to become an evil bastard and kill everyone around you. That is the constant struggle of being a Dark Knight.
