Poor Orochimaru.
Everything he has strived for, the jutsu, the immortality, can be done by the person he always craved.
Now Orochimaru has to live knowing that his dream has been taken by Sasuke. The Sharingan and the Rinnegan allowing him to use any jutsu he sees and the Immortality granted by his Rinnegan.
Orochimaru must feel bad.
