No, you just don’t have a system of morality, you have a bunch of unexamined responses to things you find unpleasant. You are why we need laws, and why it’s so vital to apply them correctly despite the fact that it gives you a sad.
You can’t legitimately call someone who’s been found not guilty in a fair trial a murderer, and as yet no one has been able to show what was unfair with the Zimmerman or Rittenhouse trials. There’s no relevant evidence that was suppressed, there were high quality lawyers on each side, and the judges made no legal errors. The verdicts were fair, and should be respected. Even if that clashes with your childish desire for vengeance against people who did nothing but protect themselves.
