I know that she did not have a easy life but bad things happening to you gives you no right to kill someone else. Especially since its still only a smart part of people that did it to her. Can I understand that she has hatred for such things happening to her? Yes. Does this mean that she should not be punished for these things? No. And please...done anything bad in their lives? She killed and tortured countless of people. We only saw a small amount of it but it was said that before she went to the people on the coast she did this inland too. Also lets not forget that she let someone else kill a friend just because he was going away from doma and after that she wanted that person to kill his parents..they did nothing! They are purely innocent.
Would you be fine if people in the real life will get away with stuff because they have a sad past? This is not robbery or not taking revenge on exactly the people that made her past horrible, she killed people only because they were born in this country. I am quite sure that you did not kill someone in cold blood in real life, otherwise you would not be writing. And since its a different time killing innocent people would normaly be a death sentence.
And the situation with the Tempered one are completely different. They are a lost cause that might call the primal back again since they are still under their influence. In a way they dont even exist as a free person anymore and the city states (not the scions) decided that it would be better for everyone if they put them out of their misery. If this is the right decision? Who knows but its not even comparable to the situation in Doma.
None of the recent city states have done anything comparable to her or the Garlean empire. They did not create a poison and experimented it on prisoners. They did not take villages apart or kill their people for no reason at all. They do not experiment on their soldiers to make them super soldiers. Do they make mistakes? Yes! But you will find no state in the world that will do everything right but there is a big moral gap between them and Garlemald and her. And even if later in the expansion we find out that not all of Doma is good, well thats just like real life. You will never have a group/race/state without bad apples in them. But those still does not give her the right to kill innocent people.
@EdwinLi: I can understand that such things happening when you are young can shape you in the wrong way but it still does not change the fact that it was her choice to kill all those people. I mean you will not let a mass murderer in real life free just because he had a bad past. You might understand them better but they still should be punished for what they did. So if her redemption is that she feels bad for it and still lands in prison for the rest of her life I would be fine with that (yet I still wonder how the heck they have survived it..both of them should have been bleeding to death from gun and sword wounds). If she gets a free pass because of it and work free at the end then I will just shake my head at this.
