A lot to process here and I can't help feeling like we're overthinking it when we resort to these psychoses.
Being that one ought to believe in people over processes we ought to examine what in the process is causing these outcomes rather than assigning blame to the people?
Of course people have responsibility over the processes but by the same token they must be freed from the blame and given the chance to improve the process.
There's gotta be a game theory approach that allows for good and bad actors to coexist given the right incentives?
