I tend to think like this: Cyberpunk the game put the players in a socio political state where finding a gun in your pocket is as common as a cellphone in the 21st century. It seems like a normal situation in regard of the ingame law. You're living in a violent world, then you'll defend your life against random goons, that's the game's rules. So that's perfectly ok.
Now it doesn't necessarily mean that your character is a natural born killer too. He/she may have ethics, maybe he/she don't want to provoke fights or murder people in command. Due to the game rules you are a nobody, crushed by the society every day, trying hard to survive by any means. You will have specific hobbies that will not be "good" in regard to today's standards (hacking for profit, blackmailing, thief, contraband, intelligence, or whatnot) but I hope that there will be a way to roleplay a character who tries to avoid direct murder as long as possible, he/she may have a choice to choose within multiple missions, avoiding the hitman missions as often as possible, or even have multiple choice of completion so you can act immorally but in distance, covering your identity (ex: hacking someone's car to make it explode so you don't need to fight his bodyguards when he's outside, or even need to sneak into his house by night). That way you can even take profit of the different character classes, it provides variety of gameplay.
Two reasons for that:
First is replay value: we need to make a fair equality usage of all the "know hows" provided by the game, for replay value. And replay value is a huge bonus for RPGs. Today I want to be a "Duke Nuk'em" Solo, tomorrow I want to sneak of hack, no gunfights if possible.
Second is the ethics: In The Witcher series, Geralt was "one" kind of character, even though he was complex he was mostly a swordsman so that justified the numerous fights. And even though, he had ethics regarding to his actions, in some way. In Postal 2 (being criticized as one of the most immoral and violent game ever), you can play entirely or mostly being pacifist, it's true ! Not killing anyone ! Ethics my dude. It must remain on the player's hands. If CP77 feels like you have some control over your character's ethics, you'll win some unwanted (but maybe inevitable) social struggle on the net.
