He never murders anyone for his own entertainment but he kills in order to let the rest of the Shelbys lead a peaceful life
BBC One's 'Peaky Blinders' is well known for its explicit content and one of the many factors which have contributed largely towards attracting a cult-like fan-following is the show's violence. Steven Knight has created the show based on the memories of his grandparents' youth, as they were part of the Peaky Blinders, notoriously known for slashing their enemies' eyes with blades.
While this signature move is carried out by almost every member of the gang on the show, their leader Thomas Shelby (Cillian Murphy) takes things a step ahead when he begins to act like a hired assassin, unlike the other Peaky Blinders.
When it comes to murdering someone, Thomas usually resorts to two ways - either slice open his victims' eyes or shoot them at point blank range. However, unlike his brother Arthur (Paul Anderson), who often tends to murder people by mistake when he is drunk, Thomas kills people for only one reason - to save the family.
Everytime he realizes his family is under threat, or someone is about to betray him and the Shelbys, Thomas doesn't take much time to eliminate that person from his life. As 'Peaky Blinders' season 5 is supposed to get even bloodier, here are the top three murders which proved Thomas only cares about his family and nothing else:Disclaimer : This is based on sources and we have been unable to verify this information independently.
