Seriously though, few role-playing games have an alignment system, especially the ones that promote themselves as being more about roleplay than levelling.
I remember one story about a guy whose group played 'evil' D&D characters, and one of them pointed out that what their characters were doing was 'naughty', but not actually 'evil'. So they tried out playing actual 'evil' characters. I can't remember all the examples he gave, but one of their plots was the kidnapping and raping of a princess. He said that campaign didn't last very long and his group found it pretty disturbing. I guess the point of this anecdote is that a lot of evil characters get played that aren't really 'evil' or close to it.
Alignment systems might help roleplaying neophytes, but if you've been around the block once or twice, they really are quite limiting. Is that noble warrior 'good' because he works tirelessly and selflessly to promote the cause of his kindred? Is he 'evil' because he knowingly and tirelessly oppresses others to do so? Is he 'neutral' because he can't be placed unequivocably in either camp? Why not just let him be a complex character on his own?
