Ultimately I think economics will convince those who just want to attack to try other parts of the game. Just randomly shooting/ killing others will not by itself be very profitable. They will be soon outgunned by bounty hunters and traders, then they'll either winge or try something else, at which point they will discover new experiences and learn or give up.
That's a very good point. I hope you're right, but in other games I've played those types always seem to gain the best equipment in the shortest space of time. I really do hope ED's economics and mechanics will disadvantage those who simply choose to spoil other people's game time.
