Actually if i remember corectlly didnt Oro said something like "i have resently aquired the new Sound Village" or something like that?? At least i got the imprestion that the village was formed before Oro came and took over..

And who to say he's not putting up a charade for the ppl that live there and they think he is a good leader?? Or that someone else is managing the village for him so to them Oro is a really nice guy..

Or if they are nice ppl living there they might not even know that Oro is there leader.. he could be disguised or that young girl/boy that he showed the 3rd in the fight could be the one that was the leader/heir to the leadership..

Or if the village consist of bad ppl there is most likely they are all thughs/mercenary/criminal ninjas that have gathered under one banner and formed a village to make a safe haeven for criminals..
