I actually created background for my character when started playing the game.
He is an Imperial, although born to Imperial slaves - poor family that sold themselves into servitude.
Therefore he hates slavery and will be actively opposing it, trying to liberate any slaves he can, if possible.
(I do it by dropping slave cargo pods at some planetary outpost and paying fine for littering)
Other than that I'm reasonable. I will trade in anything other than slaves unless I'll feel that's seriously immoral.
Been smuggling marijuana into Sol at some point for quite a while.
I don't attack other pilots, unless attacked, or bounty hunting. Will not take mission to kill civilians, or something like that.
I can't convince myself to shoot Thargoids, because I'm not sure they're not just defending themselves.
