Nietzsche's justifications have no relevance here. Removing Ortiz wouldn't change anything because the next US Prosecutor would simply do the same thing given the same set of facts. Prosecutors overreach. They have to, given the way double jeopardy and the rest of the criminal justice system works.
We get that you and the other technerds are angry about what happened to Swartz, but if you don't redirect your misplaced anger where it properly belongs (i.e., the laws that gave rise to this situation in the first place), you won't accomplish anything, and then Swartz really will have died for nothing.
* The sad part, though, is that the one thing punishment will never achieve is to make Ortiz have a guilty conscience. She and people like you will never realize that she is a bad person and should feel bad.*
Lawyers have feelings, too. Ortiz almost certainly went into the prosecutor's office to do good, to see justice done and to protect the innocent. Do you really believe that Ortiz doesn't feel torn up that a young white collar defendant committed suicide because she pushed him too hard? Because if you really believe that, then you are the sociopath, not her. She will spend the rest of her career second guessing herself with every defendant--both the defendants like Swartz and the murderers and drug dealers that form the rest of her caseload.
