Please show me proof please so I can read it. Sorry if that sounds rude.actually it showed in the manga that they killed somebody to obtain MS but i don't think whoever they killed were friends...
if you are being literal then you are right.. cuz literally oro was closest to him... but in terms of love or care.. no.. you couldn't be more wrong... sasuke hated oro.. he put up with him to obtain power.. nothing more nothing less...
