This is because his family is dead so Vinz and Hubert and possibly Abdel but we don't know since we only ever hear about Abdel, so they are basically his family.
He appears to be everybody's friend as he constantly makes jokes. Saïd (Saïd Taghmaoui) possibly the most vibrant character of the three, feels as if he has to be something, he hates change but he follows the crowd, he wants to be accepted. Koundé put a lot of effort into his role and earns his praise. But when it comes to the cut, the action and reaction is always the same and he proves himself wrong. He is always watching the hatred breed around him but never takes part. But not even a thug wants this thought about them. This is the stereotype that has been created. Hubert (Hubert Koundé), the most subtle character in the film, remains quiet and gentle, although he is a boxer or a fighter for the majority of the film. Cassel performs Vinz with brute force, not failing to portray his character for a second. Vinz is the angriest central character, but when he had his chance, he hesitates consequences are not forgotten. Like the youths feel they are supposed to hate the cops. Fear creates hate or, the thought and idea of hate. The reaction to violence is fear (which is apparent in the cops face until Hubert knocks him out). Vinz' first instinct is to pull the gun on him, this shows that the first instinct has now become violence. There is another scene in which Vinz and Hubert bump into a cop while trying to run from this.
And he has to see what it looks like, to make sure it looks "cool", as when he does kill a cop, he will get an undeserved respect by his peers. Vinz has to prepare because he is scared. This is not an action he only does once as he repeats it twice during the film. There is an image in La Haine where Vinz (Vincent Cassel) imitates Travis Bickle (Taxi Driver) in the mirror "You talking' to me?" and then points his fingers like a gun and fires. Set just within 24 hours, this is just a glimpse of the chaos.
The majority of the film revolves around Vinz and his two other friends Hubert (Afro-Caribbean) and Saïd (North African) roaming around their ghetto and suburbs of Paris. He swears that if Abdel dies he will kill a cop. One of his very best friends, Vinz (Jewish), had found a cop's weapon. A youth named Abdel had been caught and beaten by the police and is now in critical condition. It is the day after the riots on an underclass French estate (the film opens with real footage of riots with the suitable soundtrack of Bob Marley's Burnin' and Lootin'). A cinematic phenomenon so close to my heart. In my opinion, the greatest film ever made. La Haine mixes ethnics to emphasise the overriding importance of solidarity against the police. Kassovitz rightfully won the Best Director award at the Cannes festival for his film that had and still has a huge impact on French society. In 1995, Mathieu Kassovitz wrote and directed a film that showed the controversial truth "La Haine", which translates to "Hate", a film deemed so important the then-prime minister Alain Juppé arranged a special screening and ordered his entire cabinet to watch the film.
