8/10 for both Yusan Fenn and Alexandra Cinthra.
Yusan's reason. Hes on a warpath, killing and beating anyone with connections at all or reasons leading to Carliah Dakrone's kidnapping, should a trail lead to your character it would spark both the fact that you were killed by the VC, a member of the Republic which you are a enemy of, and the fact that you would be drawing him closer to the dark side by killing you out of anger.
Alexandra's reason. Already on the path to the Darkside this one would just serve as her first kill after a interesting and hard fight with your character in which she fights your character. Due to the previous hostile meeting in saving Paega the two would have known eachother previously and she could be going after you in a way to both to kill you for threatening you or even more so finding evidence that you have met and worked with Kaine Zambrano, a man she absolutely hates and wants to get back at anyway she can and eventually kill, using your character as the first rung in the ladder to him.
