Gotham may kill established characters. Seems tricky, considering this is a prequel, and the comic book villains are all such iconic characters. In an interview with EW, showrunner Bruno Heller was asked:

“Before Gotham premiered there was some discussion about how the show cannot kill any members of its cast of iconic characters, since the story is a prequel. And you had a great reply to that by saying, ‘It’s sad thing if you can only generate suspense by killing people.’ I’m wondering now that you’ve dug more into the season and are juggling all these characters, with some being more interesting than others, whether there’s a part of you that’s like, ‘You know, what if we did?’ Or is it just iron clad that you can’t deviate that far from canon?”

And his surprising response:

“I wouldn’t say it’s iron clad. You’d need a damn good reason to do it and a damn good end game to justify it. We’re certainly just learning the ropes at this stage. Not to be modest about it, but we’re still learning how to do a show this big. I’m always deeply reluctant to kill off characters simply for the shock value of killing them off. I’m not averse to cheap tricks. But apart from anything else, this season literally every actor has come through and [performed really strong]. I would hate to lose any of them. Killing off Sean Bean in the first season of Game of Thrones made everyone go, “Oh, what a good idea that is!” But I don’t think it’s a good idea if you’ve got Sean Bean. The bad one was on Deadwood, when they had David Carradine doing that marvelous Wild Bill Hickok, and then he was gone.”

This is unexpected, I don’t think anyone was expecting the death of any of the iconic Batman villains. That being said, I can’t imagine them killing off Penguin, so we can assume he’s safe. But he did mention Game of Thrones in his response, so who knows.

We recently reported that Robin’s parents, the Graysons, will be introduced soon. They, obviously, need to die so Robin can exists. Perhaps this will be the first big death of the series? Either way, we are also going to be introduced to a new character soon, Scarecrow, so Bruno has plenty of choices to kill off.

Gotham tells the story of Bruce Wayne’s childhood, long before he becomes the iconic superhero Batman, and the city he lives it. The show follows the development of classic Batman villains such as Penguin, Riddler, Two Face, and Catwoman; as well as hero cop Jim Gordon.

It airs Mondays, on FOX.
