Nice changes. Nuff said.

Well..actually not.
Negative SL does not equal to you being an outlaw/gangster.
You want to be that? Be a Black Dragon, Tsunami, Twilight Guardian, whatever.
Having Negative SL equals to you being a "chaotic evil" homicidal maniac-cyber psycho. In Cyberpunk(TM) this would mean that the goddamn police are hunting you with the intent of "shoot to kill". You know CybEx and all that fun stuff.

You killed allied/friendly/own faction people to get your SL to where it is now, if you dont want to deal with the aftermath, just don't do that stuff.
If you are in the Mafia, you don't shoot Fat-Tony because you dont like [insert what you don't like about him here] because that would probably upset your peers, who might not have a problem with him. Thats not how organized crime works. Thats how homicidal maniacs work.
And believe it or not but regardless of the social structure, homicidal maniacs usually get put down.

You guys should rejoice that all you have to deal with is is not being able to enter your P1 appartement while the police is broadcasting your APB on national television.
