Gotham, Season 3

Capt. Nathaniel Barnes:
You want to know about you husband. Was he a diseased maniac? Would he have killed you? Well, I can tell you this: I've never felt better in my life. Clearer. Stronger. More focused. Even now, I can feel it coursing through my veins, restoring my body.

Dr. Leslie Thompkins:
So Mario could have lived a normal life with it. It would have given us time to find a cure. Jim didn't didn't have to kill him.

Capt. Nathaniel Barnes:
Cure? This virus isn't the disease, it's the antidote! It's the best thing that ever happened to me. I don't need a cure. The murderers, thieves, rapists... James Gordon is one of them. When I get out of here - and trust me, I will - he'll be the first that I judge. He, and all the other human garbage that plague this city. All will be tried, convicted and executed! I will purge Gotham, and the innocents will thank me! Their savior! Their executioner!
