How far does Priestley present Mrs Birling as an unlikeable character? In what she says and does in the play, and how Priestly presents her through his writing.

What Mrs Birling says and does throughout:
Her general attitude towards others for example, refusing to help Eva Smith when she needed it the most.The phrases she uses throughout, portray a judgmental, snobbish, cruel character.Her treatment of those from less privileged backgrounds.Her behaviour with the inspector, her lack of respect for his authority.Her lack of awareness of her social responsibility or accountability to others.Her refusal to accept her moral obligations in society even after questioned by the inspector.
How Priestly presents her through his writing:
Her sense of superiority over her husband due to social class.Her behaviour with Mr Birling and being in agreement over his view of the world, suggests she is not worldly wise.Her treatment of Eva Smith and sense of superiority over her.Her judgmental attitude towards everyone but herself.Her poor treatment of Gerald throughout, due to social class.
Both the actions of Mrs Birling and presentations made by Priestly suggest Mrs Birling is an unlikeable character and Priestly very much wants the audience to dislike her and her snobbish attitude towards others.
