Best Villainy in Scifi
There are plenty iconic bad guys in science fiction. Romulans. Klingons. Daleks. The list goes on, but of all the scifi I've read or watched, I'd have to go with one particular race of bad guys: The Cardassians.
A Klingon will look for a fight. A Romulan will stab you in the back. A Dalek will blast things while shouting "Exterminate!" - but a Cardassian...you never know what a Cardassian will do. They could be your best freind and neighbor for 20 years only to shiv you when you least expect it. Or you think they are your enemy and rivil for years, only to find out the whole time they were on your side. The race is one of the most unpredicable, sneaky, and conniving race I've ever seen. A cardassian will get inside your head, crawl around, and leave behind some of the nastiest mental scars - and probably some physical ones as well, if you survive.
But I like the OP's main point. Ruthlessly practical is pretty hardcore, and as Science Fiction as a genre goes, its doing the good work of showing us one of our main flaws. Our amazingly resilient ability to keep placing systems, power and money over ourselves.
