I'm more concerned with the effects of the pardons on the country and on democracy than I am with judging the rectitude of the pardoner. Allowing the President to escape the law set a terrible precedent with obvious repercussions into the present.
I'm not trying to defend Trump. My point is that the stage was set for Trump. Abuses of executive power, of which I've given two egregious examples—Watergate and Iran-Contra—have been swept under the rug for far too long. To always "put the scandal behind and focus on the future" is to encourage future misbehavior. I would note that in stark contrast, former French President Nicolas Sarkozy has just gone to prison.
