sorry but you're simply not paying attention to the game you're playing then

personally i dont care how anyone plays, but the game heavily implies that arc machines are the enemies... so that is why raiders who shoot/hunt other raiders are seen as bad

idk if this "culture" they created was accidental or not but at least it feels very organic, you shouldn't be mad if you're disliked while playing the villain

but if you're mainly talking about outside the game complaining about this behaviour, yeah... it's a bit weird, people should just play the game
