I'm guessing you believe that a person is always completely responsible for their actions. If you are doing root cause analysis you will get nowhere with that attitude.
In the case of software RCA, but if a crime is committed then many times there is a victim. There could be some root cause, but ignoring the crime creates a new problem for the victim (justice)
Both can be pursued without immediately jumping to defending a crime
There’s many ways that people can fail where they aren’t the root cause.
These failures aren’t on that list because they require active intent.
