7. Family
Both Scarface and Breaking Bad employ family as a key theme in both of their stories. Walt's main goal at the beginning of the series is to raise enough money for his family so that they are not left penniless if the cancer were to take him. While his purpose becomes more and more blurred throughout the series, it definitely can be said that Walter is a man that holds family in high regard (although clearly not enough to stop his dealings once he has gained enough money). He clearly loves his son Walt Jr., even attempting to contact him once he has been incarcerated in the snow at the end of the series, leading to a bitter, angry son shouting curses down the phone and Walt exclaiming "it can't all be for nothing". Walt's submission in the critically acclaimed episode "Ozymandias" to Hank and his calling off of Jack and the Nazis is also a clear show of how Walt was even willing to be arrested to save a member of his family, and his horror when Hank is killed provides even more evidence for this.
Tony Montana is much less of a dedicated promotor of family care. However, similarly to Walt, he does attempt to give his foul gotten gains to them but is denounced by his mother who is appalled by his means of obtaining the money. More important to the story is Tony's relationship with Gina, his sister. Tony is overly protective of his sister and almost seems to have an incestual obsession with her, when Tony sees her with a drug dealer in a club he immediately (in his mind) comes to her rescue and violently kicks the man out. He also tells Manny, his seemingly best and only friend, to stay away from her. Eventually he discovers that the two have married in secret; Tony goes off in a rampage and shoots Manny dead. Finally, before the end Gina stumbles into Tony's office in a bathrobe, exclaiming seductively "you can't stand for another man to be touching me. So you want me, Tony, huh?" before revealing a gun and shooting him in the leg. Unfortunately for Gina, a hitman is standing behind the window and shoots her. This scene is important as it shows how Tony's bad decisions have resulted in the death of a cherished family member.
