My CMDR's actions are role played. I take his backstory and motivations quite seriously. It's one of reasons I've never had him pledge to any Power Play faction.
However, he also rarely communicates with his enemies.
Roleplay hardly requires communication though. Anyone can roleplay a silent maniac.
Don't need to be a maniac to think it's better to keep one's mouth shut.
If they don't communicate then I can assume that they don't have a reason to attack.
Then you're assuming that your particular (and fairly inane, IMO) taste in characters is the only legitimate one.
My CMDR has an identity, a story, and a personality...that he goes out of his way to conceal for his own protection, as any reasonable individual more interested in privacy and safety than fame would.
Fortunately, if you're playing the game by the rules, it doesn't really matter what you think of the motivations of those CMDRs that attack yours.
you are always at some point going to get the Cmdr's that like to break the rules. We all have some standards in what we do and everyone is different and to be honest they have that right given they have purchased the game.
My only bugbear is when you do get the upper hand, they tend to turn tail and jump away which is somewhat cowardly given they initiated the attack.
As a player, the only rules I adhere to are the rules of the game...essentially the in-game laws of nature, as far as I can divine what they are. I'm not going to exploit instancing bugs, the games lack of persistence, or cheat in any other way. Beyond that I have no compunctions about playing whatever character I choose to play.
My CMDR rarely initiates hostilities, but he has no qualms about leaving when a fight goes against him, irrespective of who started it. He's not concerned with other people's opinions of foolish concepts like courage or honor, except for how such views enable those that hold them to be manipulated. He also doesn't tell anyone of this, because the baseless assumptions of others tend to work in his favor.
