The Flash, Season 4

Joe:
Dibny seem to have gotten under your skin. Why is it so important to you that he be the bad guy?

Barry:
When I first started at CCPD, all I cared about was the rules. But, you know, in these last few years, we've locked up metahumans without a trial. Played with time and space. Messed with other worlds.

Joe:
Yeah, but what does that have to do with Dibny?

Barry:
Just that everything that we've done, we did because we were trying to help people. Keep them safe. Is that all Dibny was trying to do back then?

Joe:
"Good people don't destroy lives and call it noble."

Barry:
Did I make a mistake back then? Did I cost a good man his life?

Joe:
I don't know, Barr. He did break the law. Crossed a line. And you didn't make him do that. And you didn't make him blackmail the Mayor. But, maybe Caitlin was right. Everyone who's gone what you, and her, now Dibny's gone through... maybe he deserves a second chance.
