My thought is, WTF! It's effectively a life sentence but still too bad he can't get more than 175 years for doing this to 553 people.
Although I wonder why other physicians on the tumor board for example didn't catch on to what he was doing given he got to 553 patients? I would've thought surely someone would've noticed something seemed a bit off somewhere along the lines, maybe after like patient number 10 or 50 or 100, to question how it was this or that patient truly had cancer? Then again it's probably much harder to catch these things than I realize.
