I see what you are saying here and I don't disagree necessarily, but I see it more as a question of "how many would turn away" rather than "is there the possibility of them turning away." It is a numbers issue for me- I have no problem with outliers in any population as long as they are just that- outliers. If we saw mass defection in the clones then I would have issue, but we don't and there are legitimate- for the Empire- concerns of cost, reliability, and image of continuing to use the clones. I thought it was a kinda ironic tragedy that the great Galactic Republic uses cloned child soldier slaves, sent into battle by an order of peacekeeping mystics turned generals to fight mass produced automatons controlled by protesters of corruption controlled by the chancellor of the Republic. We can explain it as showing just how far the Republic and the Jedi have fallen- but really it was probably just not all that well thought out by Lucas. I would have loved a more thorough examination of the ethics of using the clone army in universe. In the movies it was totally glossed over(it was Anakin's journey after all and I wouldn't expect a huge debate to be prominent)TCW creates the situation to ask the questions, but never really follows through with the answers(which is a shame because they go out of the way to humanize the clones and get you interested in their characters and then leave you hanging with the realization that these guys got the ****end of the stick as they can expect to either die horribly or live long enough to become villians), and the rest of the EU swings wildly between ignoring the issues or throwing them in your face(the latter which seems to have produced massive amounts of fan hate). Unfortunately, this in universe debate is more suited to Star Trek than Star Wars and wouldn't be the first time unethical ideas or actions are glossed over(why didn't Qui-Gon free Shmi? How did Anakin get off scott free for killing and admitting to killing to Padme an entire tribe of Tusken Raiders? How can Obi-Wan falsely surrender to trick an enemy commander? Etc...) Even RL people do terrible things just from orders. I don't think you need the additional indoctrination, lack of individuality or even docility to get these results.
