Evil Karma Cannon

I believe evil karma is cannon to Second Son. I believe because of the huge change in everything. New character, new powers, new gameplay mechanics, wouldn't it make sense to also have a new ending instead of the usual good karma ending? Also, from what I have observed, Delsin never really struck me as the type of guy to be responsible. Always spray painting, lying, and everything. So, when confronted by Augustine, wouldn't it make sense for him to lie again to the police? It seems far fetched to me that the rebellious criminal would turn good for little to no reason. Just because he got powers? Hank got powers, and he still lied and committed crimes.
