Perhaps. But if he'd been brought to proper justice the first time, we would be able to eliminate him from any such involvement this time.
Sounds like self justification to me. You are not the judge. We have not been called to judge people. We can judge sin, but allow God and the Lord Jesus to handle the judgment of people. The Standard is what Michael said to Lucifer "The Lord judge you". But if that is too difficult to understand there are other verses like "judge not for with what judgement you judge you shall be judged"
