Have you read the wealth of data on it collated from literally decades of studies? It's been studied extensively. The University of Oxford, The Guardian, and the Centre for Educational Neuroscience are amongst those that have studied it in depth and the conclusion was 'there is no scientific evidence to support a causal link between playing violent video games and committing acts of real-world violence'.
Some studies noted a small increase in aggressive feelings after playing violent games but the unanimous verdict was that this doesn't translate to real world violence. They also stated the belief that 'focusing on the alleged link between games and violence distracts from the real societal issues that contribute to violence, such as media literacy, mental health support, and parenting.'
It's more likely that games provide a release IMO.
Are you familiar with 'drill' music? It's strongly associated with inner city gang violence, stabbings, etc. The police have banned it before now and tried to use lyrics as evidence in homicide cases. Much of it is about taunting 'the opps' (opposition) and year on year many drill mc's are murdered.
There's no doubt a bit of a chicken and egg scenario but I think it's safe to say it's not just an incidental byproduct of crimes/lifestyle that would exist anyway. It actively fuels stabbings and shootings due to the way gangs use it to publicly insult their rivals, who then feel pressured to react to save face/not be seen as weak. This is the reason police have banned some drill videos from YouTube and the reason why many of the performers wear balaclavas ('no face no case').
Some random lyrics:
"I chinged man's face then he fell to the floor. Coulda left him but I chopped him more. Bro didn't like him so I chopped him, chopped him. Didn't even know what I chopped him for".
"Dont need to piss on a mans grave im the reason theres worms in a mans face."
"If she's holding your wap, then she can get wacked too. Or she can get grabbed. Locked in a dark room, fed nothing but cat food."
“I see the USA takin’ the piss out of knifes, Ever cornered a man and tore out his flesh while you look in his eyes?”
“I release my stress on flesh. I carve out wounds in backs and chests.”
"My man had a closed casket, His face is still on the raq that’s ments."
"i wanna dig up lzz's grave open his coffin and spit in his face."
Just a random selection from a quick Google. Some are even worse and joking about the victim's mum crying on TV etc. I find this stuff way more disturbing than any games because most of it is talking about real events. You can find reddit threads where people are explaining the murders being referenced. Teenagers are the main audience that listen to this stuff.
