Wondering...

At this point I would say its tough to get any faction approved especialy one that is not 100% freelancer.

A faction that wants to kill all mankind already exists in the Keepers. If you want to kill evil people and threats to humanity like the Harvesters maybe you could join up with the order or be a sub section of the order?

Your chances of official approval may rise if you link yourself to something that already exists. Oh and don't forget the crazy 500 million credits.
