Voight has had one of the biggest character development arcs throughout the entire One Chicago franchise. He continues to learn and grow, leaving behind his dirty cop ways. That doesn’t mean his past can be forgotten about, as it could be easy for him to fall back into old ways if the situation called for it, especially as the debacle with Deputy Chief Reid (Shawn Hatosy) grows more serious in Chicago PD season 12.
Voight’s Debut In Chicago Fire Explained (Including His Dirty Cop Persona)
Voight And Casey Quickly Bumped Heads
Hank Voight was introduced early on in Chicago Fire, appearing at the scene of an accident that Firehouse 51 got the call to. Lieutenant Casey (Jesse Spencer) immediately stood against Voight as he realized that the driver in the collision had been drinking before driving. Well, it turned out that the driver was also Voight’s son, Justin (Josh Segarra). Being a believer in law and order, Casey fought for Justin to be charged with a DUI, especially since the driver of the other vehicle had been left paralyzed from the collision.
Throughout the first season of Chicago Fire, he attempted to bribe protection for his son, and then he went on to physically threaten Firehouse 51.

Which Chicago P.D. characters would you want to see back on the show?
While there are still several original characters on Chicago P.D., many have left the show since its debut in 2014. Personally, I’d love to see Sophia Bush’s character Erin Lindsay back on the show to give her arc some much needed closure. While I doubt it’ll happen in the future, I wish it were a possibility.
Due to his actions to protect his son and his willingness to take bribes and sometimes commit crimes to solve a case, Voight was quickly labeled a dirty cop. During Chicago PD, we learn that Voight took the murderer of Alvin Olinsky’s (Elias Korteas) partner out for a “boat ride” to kill him to get revenge rather than wait for justice to be served.
How Voight Eventually Won Firehouse 51 In One Chicago
Voight Proved He Could Be A Good Cop
As more people around him realized that he wanted to get the job done and protect the most vulnerable in Chicago, they were able to turn their backs on some of his more brutal elements of his character.
This was the turning point for Voight’s character, as he proved that he did want justice and that his dirty cop actions were linked to the need to get justice. Voight justified working with unsavory people and do illegal things if it meant protecting the people of Chicago — or his own son as the initial introduction proved. As the members of Firehouse 51 realized that he wanted to protect the most vulnerable in Chicago, they were able to turn their backs on some of his more brutal elements of his character.
When he has continued to lie and act against the law, it has been to protect his own people, and he still makes it clear that he will do that, gaining the protection and loyalty of his team, including even Antonio Dawson, with whom he shared a tense relationship at the beginning. How far it’s evolved is a testament to Voight’s character growth in Chicago PD.

Why Voight Doesn’t Follow His Best Principle In Chicago PD: “Tell Me The Truth So I Can Lie For You”
Chicago PD season 12, episode 13 reminds the audience of Voight’s leading philosophy, but it’s something that he doesn’t abide by in the show.
