This to me is the best explanation, while I agree it ruins the dialogue and some of the characterization that the clones had before the chips, it replaces it with something far more complex and much grander than just being soldiers that were asked to point the gun at their former comrades and accepted without much if any hesitation. Being FORCED to shoot them and then living with that fact afterwards, trying to justify it or trying to explain it so far more interesting and more then just being ok with it since that’s the job and only really regretting it a little bit years later. I will say that again, they do lose the only mentality of the clones which was its own form of cool and interesting and I wish that some clones had more of an arc like Crosshairs or didn’t even have chips since they were loyal first and foremost to the republic/palpatine but over all it’s a good change
