Sometimes fictional stories and setting contain interesting and novel ideas that might be used as inspiration for real-world thought on how things are. The point being "used as inspiration". Star Wars is really shitty fiction to begin with, and if you take something directly and literally out of there and try to make it work in real world...it just doesn't work. At best you might get your head wrapped around it so hard that you believe it works, and from that point there is not a long road to the mental asylum.
As far as the "real world influences" behind this "Kreia's philosophy", I would hazard a guess that someone has read some Satanic Bible, and perhaps one or two paragraphs out of the "Might is Right". Both are shit, for more reasons than I care to go in to here.
