I only plan to have one toon unless for a mechanics reason a second toon comes in handy like gathering in darkfall or scouting in EVE Online. 99% of my time will be in pirating and PVP activities. I've always liked EVE Online philosophy on good versus evil. They don't exist, you are either NBSI( Not Blue Shot It) or NRDS (Not Red Don't Shoot).

In Darkfall we are NBSI or NAKI (Not Ally Kill It). Good and Evil were mainly created by games that had a good and evil side. Games like Eve and Darkfall don't have that built in lore mechanics wise and neither will Star Citizen.

So like Zhou said I don't see a reason for a good and an evil guild in game.
