i dont know why people would assume that the leader of Atasuki is someone stronger then everyone, Gattou was Zabuzas leader and we all know he was a weakling.
Also ordering someone to kidnap someone isnt as bad as experimenting on them the way Orochimaru did, as far as we know at the moment he is the 'evil', we cant make assumptions on people we've heard NOTHING about.

Also Atasuki doesnt seem to have a ascending command line, they're probably a democracy on their decisions
