I can understand your viewpoint. Perhaps not agree fully, but I can understand. Personally I believe that when I was brought here, it opened a new path for me. My path back home ends, and I understand what I need to do. On the principle that I already do that, I much prefer to walk this new path. Maybe it'll end the same, maybe it won't. The force is funny that way, it'll never really tell you what the path is.
Don't know much about these darkspawn, and if you feel there's a danger for you or others I won't stop you from going home. I would miss you, but I can't make anyone walk a path they choose not to.
