People that don't like him are just trolling.
You are correct that his last memory of her is when she was 14, maybe 15, which isn't even pedophilia and in some parts of the world is marrying age; used to be the marrying age in America about 50 years ago too.
He isn't either. He has no sexual desire for Sasuke, he just wants to possess his body to become a Rikudou.
Having dreams about a 13 yo girl when you're in your 30s doesn't qualify you as a pedophile now? What is the world coming to?
14-15.
Did he dream of her naked? Or performing sexual acts? Candle-light dinners? And in his dreams of her, he's young again too.
You're the one who should take your advice before passing them, pal. Obito did all this for Rin. He was attracted to her. So allow me to pass on your advice to yourself: ''learn to say something else instead of that''.
He did it because he
loved her.
Do you want to bone your mom?
She'd also be the same age as him if she weren't dead.
