Accountability  It is a fundamental principle of morality that individuals should be held responsible for their crimes – that is the reason why we, as societies, have criminal law.  Prosecuting people – holding them responsible for their crimes – is a moral imperative. We all wish to live in a society where everyone is equally accountable when they commit crime as one in which not everyone is held to account is fundamentally unjust; it creates one rule for the powerless and another for those who are ‘needed’ to help create peace. This would simply incentivise people to try to make themselves indispensable strongmen – not a sustainable basis for a peaceful society.
