For those saying nagato and obito are similar in any way, i suggest you start reading this one manga called Naruto.

NAGATO -Had his parents killed before his eyes(by konoha nins). (He is still a good guy)
-his village was destroyed because of war(i guess). (He is still a good guy)
-He became a begger asking for food from door to door, he had no friends or companions, he found a dog, his only companion in life.(He is still a good guy)
-Dog dies.(He is still a good guy)
-Meets yahiko, they form Akatsuki, many of their companions die.(He is still a good guy)
-Yahiko is forced to kill himself due to a betrayal from someone they respected and Konoha nins.(At this point he snaps after many years and realizes there is no hope for the word he also decides to destroy konoha).

OBITO -Crush dies(At this point he snaps after 1 year and realizes there is no hope for the word he also decides to destroy konoha).

No similarity.
P.s Obito is more evil than Nagato.
