I dont want to destroy my charater trying to write a story to try explain the shift in alligence. There is no way to reconsile the OOC decision with IC motives and persona. So it seems that the choice is either roleplaying and writing stories while spinning ships in station, or parking the persona one side while doing other things.
Hm. It seems as though there should be a way around this.
Maybe you've already considered and discarded all of these (please forgive me, if so), but....
IF NOT IMPLANTED:
- Disillusioning experience / loss of faith / qualms
- Error in consciousness transfer, resulting in sharp personality change (not unlike brain damage)
- Brain damage
- Feigning any of the above (eez spai!)
- Capsuleer dementia (character realizes he no longer cares about the fate of Eve's NPC's any more than the player does; apt to make a dent in the loyalty of any idealistic Nation follower)
IF IMPLANTED
- Software bug
- Virus (could be from outside or otherwise stem from some odd happening with Nation itself)
- Hardware malfunction leads to sharp personality change
- Feigned change (eez again spai!)
A lot of these are reversible-- even retroactively-- if you decide you want to return to your old role. For instance, you could go with the "copying error," which is believable but very difficult to confirm, then decide later that your character faked the whole thing to go gather intel. Likewise, brain damage could be healed (yay super-science!) or hardware repaired.
I don't know if any of that is helpful, but I thought I'd toss it out, just in case. Good luck, whichever way you choose to jump.
