If you want to be a psychotic KoStard, join the Psychopaths. That's the faction designed for that. Independents are meant to go out there and scavenge, not give a crap about the war between the factions. Maybe somehow get roped into it anyhow and eventually having to decide to join. Like in Skyrim.
I don't want to be labelled due to the idiocy of others. So please, if you want to go around randomly killing people, join the Psychopaths. But remember, even they have "rules".
