Messages and Values developed later in The Krays

Message - Ronnie is insane.
Out of control at times, no one attempts to control him. He does extreme things, shoots Cornell in the head in the pub and cuts into a member of his gangs mouth.

Message - Reggie smothers Frances (male domination)
Frances wears the gloves because Reggie likes them. Frances says she doesn't know what she likes anymore, she only knows what Reggie likes. She doesn't go shopping herself, Reggie buys her clothes that she doesn't chose herself.

Message - Mental illness and crime doesn't mix, can have catastrophic consequences.
Ronnie: enjoys harming others due to mental illness.
Frances: harms herself due to mental illness as she can't cope with crime.

Message - The failure of police to control the criminal activity.
Ronnie shoots Cornell in the pub with many witnesses surrounding them. Nothing reported, no police action. The Krays don't hide, everyone knows where they live, police never go for them.

Message - Ronnie is jealous of Reggie.
When they are in the club and Ronnie lashes out to get Reggies attention, as Reggie is across the room speaking to a girl (Frances).

Message - Reggies loyalty lies with his brother.
When Frances meets Reggies family, he leaves Frances to go for a meeting with his gang rather than sitting with his wife. He then goes out with them and leaves her with his family at the house. Frances is clearly uncomfortable with this.

Message - The Krays are invulnerable.
They become more powerful throughout the film and aren't scared of anyone or anything. They don't face any consequences to their actions.
