Dakkus I'm like you! I also play a lightside Jedi Knight!.. I enjoy playing him so much! And like you I am very concerned with RP, the only darkside thing I did was romance. But I had already added that into my character. As for the end of ch.2 I didn't think it shown poorly on my character! For me I felt like it gave him more insight into both what the Emperor is capable of and I think my character would learn from this and continue to live in the light in order to preserve good because now he truly knows what the darkside can do to a person. That is my opinion, but I highly suggest continuing the story, I haven't finished it yet but I enjoy it so much! Good luck! May the Force be with you
