Yeah but being able to help and choosing not to because of some nebulous possibility that it will turn out badly in the long run is just as presumptive as sticking your oar in everywhere regardless of whether it's needed. Like at that stage you get into such abstract thinking that there's no point to doing anything. Maybe in five thousand years helping Primitive Race X will have turned out to be a terrible idea, but that's for people in 7350 to worry about.
Oh, and I don't think Into Darkness is Trek's finest hour, but it's still a movie I enjoyed a whole lot.
