 * / i can actually understand nagato, he did it so that he could stop the pain and bring peace, but obito did this because he lost Rin, he only hhelped by the project because he could have Rin back, like sasuke wanted revenge because he lost his clan and family, if he gained her back i think he would have stopped :)
