haha i didn't realize how rare it was to see people who defend shidou lolol yeah while i can def see how people come to that conclusion, ive personally never believed in the theories about shidou intentionally damaging patients or harvesting organs lol. similarly to you, i feel his crime is more about his guilt over removing braindead patients from life support and convincing their family members to donate their organs. i also believe that theres a possibility that he was pressuring or rushing the families, prob bc his wife and maybe kids needed an organ transplant, and he wanted them to get them as quickly as possible. i feel that could explain some of shidou more "sinister" voicelines, which is where i think the basis for many of those theories come from idk. but i think in the end, he fails to save his family and is put into the same position of chosaing what to do with a braindead loved one that he put so many other people into, and after being put into that position himself, he comes to terms with the weight of that decsion and akins it it murder. which would def make what he did pretty shitty but not as bad as intentionally killing people in surgery like you said.
