you feel sorry for him , why?
He abandoned all his friends because one of his "friend" died. Like seriously that's BS .
He killed innocent people. He is responsible for minato and kushina's death, he is the reason sasuke and naruto became orphan. He is the reason 500k shinobi died in the war, he made many wives widows and many children orphan.
As a kid living at the time of war, he completely realizes what war does to people and what war did to him still he goes on and starts yet another war.
Obito is a mass murderer and i don't feel sorry for him at all. Actually he deserves more punishment.
