Joseph Falk

Joseph Falk, also known as The Savior. was a psychotic vigilante who gave death sentences to those who he believed had wronged the Glades. This was caused by the murder of his wife during a robbery.

Biography
Joseph was born in Calvin City in 1980, and moved to Starling City at the age of 6. He graduated from P.S. 149 in 1998. Living in the Glades, he picked up a few odd jobs, among which included a car wash attendant, and a custodian at St. Therese Academy. He met his future wife at the latter, and they married in 2005, when he took a job at the Starling City Department of Transportation as a computer technician. He retired in April 2012, following the death of his wife, subsequently falling off the grid.

Joseph began picking out people who he believed made the Glades a horrible place, and broadcasted them to a website, Glades Betrayed. Among these were John Nickel, Gavin Carnahan, and Roy Harper, the former two whom he murdered on-camera on the site. Oliver Queen discovered his use of the abandoned Starling City subway and killed him before he could kill Roy.

Trivia

 * There is a character in the DC Comics called The Savior, a man called Ramsey Murdoch who started a personal crusade against Superman, believing him to be evil. The two are seemingly not related in any way.
 * Joseph Falk could also be based off the Batman villain, Anarky. Anarky would kidnap business elites, and would put them on a public trial, their trials would be broadcasted on a television program. Like Joseph Falk, Anarky believes he is saving the world.
 * Joseph Falk claims that he was inspired by Arrow and that they are the same, however there is a difference, Arrow only kills his enemies in self-defense, or to save the lives of innocent people, but tries his best to avoid it, and never acts as judge, jury, and executioner, and willingly gives his enemies, a second chance.
