Choosing your own path?

Alma 41, verse seven says:

These are they that are redeemed of the Lord; yea, these are they that are taken out, that are delivered from that endless night of darkness; and thus they stand or fall; for behold, they are their own judges, whether to do good or do evil.

It looks, like, from this verse, that the only souls who are going to be their own judges are going to be those who have chosen righteousness--those who choose wickedness are consigned to torment and have no part in their own judgment--only Celestial Bodies judge themselves...

So, you're your own judge, and you're righteous, so you have the mind of Christ, so who is going to be your judge?  Christ--"Christ in se" or Christ's judgement coming through you...  

The image that comes to mind, though, is of those latter-day-saints who are too hard on themselves or who sound like they are being too hard on themselves (whether or not they actually are or whether their words/attitude is actually that which the think or believe); is it really an affect?  Is it actually righteous?  And, the point of being judged of yourself, with the same judgment that Christ gives?  Wouldn't that mean that the affect is disingenuous?

Or, whosoever is righteous can walk wherever they want WITHIN the path and be saved (see vs 8)...  some choose to walk on the path of exaltation, others won't, but walking on the path will take you to the Celestial Kingdom!  Once you're in the Celestial Kingdom and have been resurrected with a Celestial Body, then, except for an exalted body, couldn't you choose different paths?
