Yeah, utilitarianism also isn’t going to always (or even most of the time, depending on the flavor) be convergent on “pro-social/cooperative behaviors”. I think this is because it’s easy to forget that while utilitarianism does broadly work towards the good of the community, it does so in a way that aggregates individual utility and takes an individual’s experience to be the key building block of morality (as opposed to something like Communitarianism, which centers the good of the community and the sort of behavior you mention as a more base tenet of its practice). How much it will be convergent with these behaviors is certainly up for debate, but so long as the behaviors mentioned above are only useful towards increasing aggregate individual utility, you will have many places where this will diverge. This is perhaps harder to see when you imagine a polar extreme as you mention “lying or being an asshole to people all the time” but I don’t think anyone is worried about that for utilitarianism. More that they might follow down a successive path of deceit or overriding of other people’s interest towards what they see to be the greater good (i.e. “knowing” a friend would be better off if they didn’t have to bear the weight of some bad thing in the world that relates to them that they wouldn’t find out about if you don’t tell them—this seems like the sort of thing utilitarianism might justify but maybe shouldn’t).
