I’m inclined to consider it far more counterintuitive to think ‘if this person experiences overall slightly more negative than positive affect, but very much wants to live, and find their life meaningful, and I painlessly murder them in their sleep, then I have done them a favor’, which is what a purely hedonist account of individual well-being implies. (Note that this is about what is good for them, not what you morally ought to do, so standard utilitarian stuff about why actually murdering people will nearly always decrease overall utility across all people is true but irrelevant.)
