You would have one opinion, someone else has another. But Charlie can't be in a a quantum superposition of jailed and free.

If whether Charlie is punished or not is entirely up to me then if I think he deserves to be punished I will do so; if I don't I will not do so. If I have to persuade someone else to punish him, then I will try. If the legal system is doing the punishing then I will advocate for laws that agree with my morals. And so on.

if there is no objective fact of the matter about moral claim, there is none about who gets punished or rewarded

No. There is no objective fact about who ought to get punished or rewarded. Obviously people do get punished and rewarded: and this happens according to the moral values of the people around them and the society they live in. In lots of societies there is near-universal acceptance of many moral judgments and these get codified into norms and laws and so on.
