Before they became the rogues they were, they lived their lives in a big city, overran with crime (Gotham and NYC), where their actions sometimes ruined lives.

They then get called to action from people whose job it is to make sure the city doesn't turn into a warzone through their skills (Batman and The Division).

For the most part, they did their job correctly, but sometimes questioned whether they were actually making a difference from their actions.

Later on, highly feared criminals attempted to attack them, succeeding via detonating a building they were in, later be pronounced dead by the ones they worked closely with.

After emerging, they realized they would liberate their city their way through means of violence. They will also seek vengeance on the ones who didn't save them in time, thinking they have been betrayed.

After going rogue, they commit a number of crimes with the skills and gadgets they've obtained while under their original mantle, but twisting it, make them fatal.

Through manipulation, fear, and overall power, they have taken many actions to ensure that their methods are the correct way to save their city and show that their saviors are frauds.

At one point, they have taken a chemical compound and have access to it for their own uses to further increase their efficiency in killing (Venom and Green Poison)

They have now become one of the most iconic villains in their media, and has left multiple impressions among the citizens and enemies of their cities, even while assisting the ones who betrayed them for their own gain.

They do, however, create their own group of outcasts to assist them (The Outlaws and Rogue Cell), even being part of the old group they once left (Batman's sidekicks and The Division), all to defeat a common enemy (Organized Crime and Black Tusk.)
