Did a lot of evil shit. But let's full face it these ain't one of them.

No one knows what anyone looks like. Madara has only been gone for about 60 years. People are still alive that actually met him and there are probably still artist renderings of him for history purposes. despite this, Nagato, Hanzo, and Onoki, who might not have fought him, but he was definitely a genin around the time Madara was still running around, all think Obito is him despite being a different height, different hair, different voice, and different powers. The only thing going for him is that he's strong and has a sharingan. and that's not even touching the fact that Naruto and Minato are the only two blonds in konoha not related to ino, and no one realized?

Medical ninjutsu. In the beginning of a series, it was well established that medical ninjutsu required both really fine chakra control and knowledge of the human body to make sure you aren't rupturing their lungs or giving them cancer. Naruto, who is established to have mid level control and 0 anatomical knowledge can just whip Gai up a new body. Then there's Obito who had literally half a body then got saved because Madara obviously has a medical degree, how else would he be able to integrate Hashirama's cells into him presumably before cell theory existed. And let's talk about eyeballs. Let's just assume for the sake of the argument Rin was a semi-trained medic who did Kakashi's eye swap in the middle of a warzone, and Kakashi still had a bum eye for about 25 years. Zetsu plopped Madara's eyes into baby Nagato despite a grown man's eyes being shoved into a baby's skull. Then Obito and Madara are playing hot potato with their eyes. Do Sharingan just have no nerve endings?

And speaking of jutsu that should be more important than they are, fuinjutsu. We know the Uzumaki had it and they made extra strong jinchuriki, that's why they were killed. We know you need it to make a proper jinchuriki or the tailed beast will pop out. and we know you need to write stuff on paper for it to work, that's why Jiraiya has his big scroll and Tenten has her twin dragon thingy. Except Minato can just touch stuff to make his teleport points. The sage can just plop the two most powerful seals ever on your hands and it's just two little temporary tattoos. Madara and obito don't need any seal because they can just plop the whole ten tails inside them despite not being uzumaki and there being no seals period. And you'd think for such a powerful and useful ability, more people would have it. it literally fits Sakura's mindset way more if she were a seal user way better than a medic.
