possible, I think 4w5 would work better thoughOrochimaru seems more like a 5 to me.
his main objective is status, recognition and respect from others. 7s don't care about any of that. we just wanna have funNaruto - why 3 over 7?
I'm not sure what else he would be. he's not a 9, not a 2, not a 3, not a 4, probably not a 5 or a 6 and definitely not a 7)No way, Kakashi is not an 8. I doubt 1 as well. Not sure what he is though.
