I think it is wrong for Trump or Barr to pardon or reduce Flynn's sentence. If there is evidence he was railroaded there should be an appeal and a new jury trial. If Trump or Barr are involved it is logical to assume their action is bias. The reason to pardon or commute his sentence is to get him out of jail without risking the new evidence is bogus or can't be proved and so new evidence confirming Flynn's guilt doesn't surface.
