#Foolishness
I honestly don't see what going on, bringing Sauske back doesn't eliminate his free will... If he was ever forcefully taken back, even in Naruto "broke each one of his bones", he'll heal up and leave again. Like you can't force him to stay... if Sauske doesn't want to be at the village you can't stop him from leaving. And even if you were to go against his wishes and forcefully keep him there over watch 24/7 what are you accomplishing?
Sauske's mind was (until recently) set on leaving. Bringing him back by force really changes nothing... just something I never understood .-. It's not like bringing him back physically changes him mentally.
