If you want to equate Obito to Sasuke then first Obito would have to have a somewhat caring family and then have Rin come in and slaughter all of them and when Obito asks her y she would pretty much say because she felt like it. Then she would tell Obito that there is nothing that he could do because he is a weak little priss and before she would leave she would place him in a genjutsu where in Obito had the enjoyment of watching her brutally murder his family over and over for 24 hours.
If you can honestly equate the emotional stress of this experience to Rin simply dying and Obito knowing all along that she did it to save Konoha as a Kunoichi then I don't know what else to tell you
I still wouldn't make others suffer because of my own and discontentment
To compare Sasuke to Obito, first you have to have him grow up for most of his life being shown no love at all, and then finally meeting one person that cared about him. Then, he makes about three more friends, going so far as to sacrifice himself to save the friend (let's say it's Naruto) and the girl (let's say it's Sakura). Sasuke' saying wish is for Naruto to protect the first person to show him love and compassion, the person he loves most and holds dearest to him. About a month later, let's say he discovers he's survived, only to find an evil old man telling him everything is pointless. He ignores the old man's bs because he knows he'll protect Naruto and Sakura. Once he's finally healed up, what's the very first thing he sees? Naruto himself killing Sakura. Now he finally realizes the old man's words about how pointless and futile everything was, because his sacrifice ultimately meant nothing. Then factor in about one to two years to train with this Palpatine of Naruto, and he's had enough time to be completely indoctrinated, as well as enough time to stop caring about his mentor, his mentor's wife, and the so-called friend that failed him, along with all this, he's been fed delusions that he's the savior of the world.
