With regard to the evil and fulfilled thing, I'll admit that that's just the convention of most stories, mixed with my own personal biases, in that I genuinely believe one cannot be evil and emotionally fulfilled, something I feel is borne out even in real life. But that's very much not in the purview of this discussion. I fully expect Larian to present options for keeping or making some companions evil, or having companions that are only ever evil, I was mostly arguing as to why people would want to see evil characters become good within the story. Ultimately while I stand by the observations I made, I think Lae'zel only really needs some very mild tweaks to really work. Even something as small as including a few key lines scattered around and not really changing anything else would have her on the right footing.
