Call me a sociopath but I played renegade every time and from what I remember it mostly doesn't change outcomes just the way you talk/act, mostly

Now knights of the old republic? THAT game you could actually be evil

In my first playthrough, I didn't even know about that game mechanic and was all over the map for the first few, but it occurred to me fairly soon afterward that very few game publishers, if any, would sign off on most blatantly evil/psychopathic options for a protagonist. I mean, I'm sure someone pitched a SW storyline that comes close to Ani's schoolhouse slaughter fest, and yet? Nada.

Not that I prefer that as an option, just that it certainly made the "Renegade" path seem less likely as diverse in its scope, in comparison.

Though, IIRC, some of the Paragon choices did feel too ruby-lensed and blithe (what's the opposite of edgelord?), but maybe that's just me.
