If that were true, violence wouldn't exist. Violence is based on the belief that you're stronger than the other person, and even if not, that you have stood your ground.
GENERALLY, not every human being everywhere. Violence exists because of different reasons (drunk people, anger management issues, toxic masculinity, bullies at school with shitty childhood taking their crap on others etc.) that generally has nothing to do with violent entertainment. Sexual harassment & assault exists, in big part, because women have been (and still are) portrayed as sex objects for men to conquer on many fronts of society. The entertainment we consume has a big part in that (it's not the only reason these things happen, obviously, but you can't deny its significant part in all of it). This is especially true in this day & age where a lot more people have more time & money for leisure and entertainment is widely available to people on all walks of life.
I think you're completely on the wrong track here. The games you wrote are outliers. They are much less popular than other violent games because they show "dirty", unjust violence, and that doesn't appeal to many people.
I know they are outliers. I just brought them up as examples of violent video games that can have some negative qualities to their violence that I'm personally not all that ok with. It's not just violent, it's violence with a deliberately hateful ideology behind them. You aren't fighting Nazis in WWII or other more fantastical settings, you aren't protecting your life from modern day pirates or mad-men in control of a bloodhungry mercenaries who will shoot you on sight.
All this said, I DO NOT think someone who plays Hatred is going to go out to the world and start shooting people just because they played Hatred. It can kind of feed into some psychopaths sense of joy they get from merciless killing of innocent people, but all in all a lot more needs to be wrong with a person for them to go shoot people.
Games with a heroic protagonist on the other hand who is shown to defeat his opponents with violent means are the most common story setting of all. No one who uses violence in real life thinks he's the bad guy. Like you say, one or two of these kinds of fantasies don't make much of a difference at all, but if this stuff is around us all the time in every type of media, I wouldn't be so quick to rule out an influence on our way of thinking.
Yes, and a vast majority of people will never be in those situations nor do most people possess the level of skill to pull of anything like what is done in movies/fiction, so there's really nothing in those games to take much example of. They are generally extreme situations that very few people will find themselves in.
99,9999% of people who play these games are not going to be fighting against criminal overlords in real life. They aren't going to be stranded on a remote treasure island that has modern pirates after the same treasure they are searching for that they'd need to fend off. The scenarios are so far removed from real life. No one is taking any influence from Uncharted's form of violence. Some men may be a bit too quick to resort to violence when push comes to shove, but the average man who uses violence still needs a reason for it.
Just because Bond defends himself against bad guys in a movie through violence doesn't mean someone is going to start going all James Bond on every man and woman they see on the streets. There still needs to be something to instigate that violent behaviour, whether that's something as dumb as perceived insults to their character or actual need for self defense. Very few people act violently for absolutely no reason.
On the other side of the isle, sexually motivated interactions with people you are attracted to are a common part of most humans' lives and as such people get more changes to act on what they've been influenced by in entertainment. People see Bond being "determined" getting the girl, people see Bond being charming, suave, and that can have much more of an influence in how men think women should be wooed IRL than any violent piece of entertainment has on violent behaviour. These are situations men can easily (try to) replicate in real life. The women fell for Bond's insistince, not taking the first few nos for an answer and "charm" in the movie so it MUST work for them too.
Again, a lot of men who sexually harass women do not even see it as sexual harassment because that's how they've been taught to think by society at large for their whole life (entertainment being a big culprit in that). They are just "paying a compliment" or think that them hitting on women "should be taken as a flattering suggestion." Women in fiction aren't complaining about sexual harassment on screen even when that is clearly happening, so a lot of men don't interpret it as such and go on to copy that kind of interaction IRL.
