Okay, so I realize that this is a bit late for Bioware to do anything about it now, but possibly it can be implemented more in future content.
I've played an Inquisitor to level 26 and an Imperial Agent to level 14, and I personally find it hard to feel like a "Good Guy" when I pick a conversation option that I would say in a very moderate way, but my character says it like a threat. It doesn't give me Dark side points, but I still don't really feel like a "Good Guy", which kind of kills the immersion factor for me. I like the story line for the Inquisitor quite a bit, so'll I'll keep playing anyway, but maybe with future content, the characters can have more real good things to say instead of just "controlling" their inner demon that wants to kill everything.
This is just my two cents, does anyone else feel this way?
