Granted, your curse is that all your dreams come true and you experience the most exquisite pleasure you will ever know. I wish I could be instantly good at everything I attempt.

A point which I haven't seen anyone make yet is the nature of soulcasting that we have seen so far - through Shallans eyes. It involves arguing with a sentient aspect of the object and convincing it to transform. While I wouldn't argue that this is the only way - the soulcasters used by ardents don't appear to be this complicated, I think it is something to consider. If Jasnah soulcasted these men, the possibility exists that she was able to "touch" their minds and thus know without a doubt that they were guilty of the earlier murders. I'm not going to make a big argument about it and that being a case for it as a moral action. I see her actions as justified personally. But I also think that her spren must have a very loose set of morals/honor/whatever you want to call it governing the bond/powers granted to Jasnah. On the night her powers manifested she was returning from, or on the way to, a meeting with an assasin who, it is reasonable to believe she has used for actual killing. She also said she maintained relationships with all the prominent assasins in order to protect her family, by having people killed - most likely. Mraize says she has had several members of his order (the ghostbloods) assasinated. I am solidly in the camp that though Kaladin's spren/oaths/bond requires him to be extremely honorable (his spren is an honor spren) the other orders will all function very differently.
