sasuke is going to destroy leaf when he should destroy madara for betraying the clan. and the clans downfall to begin with.
and obito well same madara probly sent those ninjas and setup rin knowing obito could help him with his sharingan. so both fighting for messed up caused.
sasuke will never get his clan back and cant figure out his clan isnt extinct reproduce and revive ur clan dont kill leaf then that will kill ur whole clan. the whole emo thing hasnt worked for him and he gaining power to advenge his family. ok advenge his family but then go against the only person truly cared his brother. yeh he like i dont care brother i am still going to kill everything you loved brother to avenge my clan. ok to advenge his clan destroy everthing his brother loved his only true clan member that cared for him. instead avenging his clan sounds like defiling his clans beliefs and honor.
and obito is messed up. making everyone in illusion wont bring true peace cause everyone be in comas basicly in fake life. there be no free will and whos say madara wont twist it to make him king or god of world. this obito being backstabbed in back someway to live a life with no free will and no true reason. his goal makes everything he fought for worthless. without free will all he did wouldnt have ment anything.
