This is a good card.As far as you have behaved well, you have nothing to fear!!! It's time justice to be done! You'll get just what you deserve... Your work and your efforts will be recognized and recompensed!
Very positive to me...(one of my favorites as well!!!)

this woman is intelligent why her decisions are trusted, powerful but honest

Although this card is justice, it does not give me any good feelings.  I don't know why but it just feels so harsh and ungiving.  It is what it is.  Those are the rules.  There is no wavering from the set of rules.

The scale would weigh the decision made to determine the outcome of our future.  This is a universal justice.  I see it as a sorta karma.  You reap what you sow.  Don't go belly aching about the decision now.  It was made due to your past actions.  

The decision will be fair and just, BUT it is a universal justice (not man made).  Basically, the choices we've made have consequences.  Now is the time to be judged and given an outcome based on those choices.

Maybe I don't like this card because I am worried about my own karma  

I see this card as the end result of what goes around comes around-justice or judgement.  So if you used the good fortune/luck given to you in a positive way, you will be justified to be given positive back and same with the negative aspect.  If you handle bad things happening to you in a negative way that will affect things as well.  Punishment or reward

Justice, to me, represents both judgement and punishment, hence the sword and the scales. This, to me, represents karma more than the Wheel. Where as the other represents events, and the passage of time, Justice is the meaning behind the events.
