As we all know sasuke got the CS when oro bit him. and we all know when oro was killed by itachi, sasuke lost all of oro's powers. now there has been a debate about weither or not sassuke lost CS because even though orochimaru gave sasuke that power people believe he still has it because it was already in his body before he absorbed oro into his body. but here's the thing. CS was still oro's because it was created by the enzymes from his bite and as stated by the sound four it causes the victim to loose free will and be brainwashed by oro so it shows he is directly invoved with the effects of CS so when he died at the hands of itachi all the powers sasuke got directly from absorbing oro including CS left his body due to the fact it was created by oro in the first place.
this shows sasuke doesn't even have the seal anymore Naruto 396 | Read naruto chapter 396 manga online
now juugo wont lose cs because it was his in the first place and his was the orginal and juugo says himself that all others effected by CS were only copies of himself created by oro and as we know all copies don't share everything the original has. (this due to the fact no one else goes crazy when they use the CS like juugo does)
he states that all others are copies here
