Going to serve my username and point out the hypocrisy over how everyone loses their shit over Orochimaru but not the other characters:
"Unethical human experiments"
Tobirama did it too. Only he knows what kind of atrocities was required for the invention of edo tensei.
"Killed so many innocent people"
No shit captain obvious, last I checked the five big villages bulldozed entire smaller "weak" villages to the ground during wars, civilians and all. Don't trust me? just ask Nagato and co
"He manipulated and abused kids!"
As if konoha doesn't send scores of children into forests with deadly wild animals every year even during peace time as examinations. As if the entire system isn't built of forcing children into ultranationalist ideologies, raising them as child soldiers.
Yes, Orochimaru should've been sealed away in that blade away forever as retribution for his wrongdoings, but are we seriously going to traipse around acting like his actions were unique to him? That he wasn't quite literally raised in environments normalising such horrific acts?
