Defnitly opjective criminal actions like murder, war criminal activities more have to be responded to. I am a humanist and would therefore argue, that the monly moral response is taking away their freedom. Putting them into a prison. Since every other action would need someone else to commit a crime. So it could not end.
And it is well backed with human rights.
And I think every person has to be viewed as innocent until you got proof that they are not.
