Succeeding in any aim gains sfik, as long as the aim is not trivial. Subjugating a group of other Kif to build a spaceship is a suitable aim; especially as you can then use that ship afterwards to accomplish more aims (and you've already got a subjugated crew).
But yes, two Kif, alone, are not a stable equilibrium. (Among other things, they only eat living food, and not plants. Two Kif with no other live animals around are the only source of food for each other - they have no qualms about cannibalism). Depending on the individuals, however, they may well decide to cooperate temporarily, and rebuild, in order to increase their long-term odds of survival. (They don't care about their legacy, however. Being killed is The End. It's a bit of a mystery why they would ever try to have children). Long-term survival beats a temporary sfik gain.
EDIT: Incidentally, if it's possible to have negative sfik, does that mean you can gain sfik by helping the disadvantaged?
Not directly - that's a trivial aim. But it's perfectly within the Kif character to offer the disadvantaged a deal, something along the lines of "Join my followers, and I will help you now in order to obtain your labour later; betray me later, and I will kill you" and then use the extra footsoldier to gain sfik in some way. (If the disadvantaged was disadvantaged by a common enemy, they might simply turn up, help the poor fellow back on his feet, let him heal a bit, then give him a gun and point him at the guy who originally hurt him).
I'm not sure that it's possible to have negative sfik without dying. It's certainly possible to have zero.

Part of the sequence: Rationality and Philosophy
Bertrand Russell
I've complained before that philosophy is a diseased discipline which spends far too much of its time debating definitions, ignoring relevant scientific results, and endlessly re-interpreting old dead guys who didn't know the slightest bit of 20th century science. Is that still the case?
You bet. There's some good philosophy out there, but much of it is bad enough to make CMU philosopher Clark Glymour suggest that on tight university budgets, philosophy departments could be defunded unless their work is useful to (cited by) scientists and engineers — just as his own work on causal Bayes nets is now widely used in artificial intelligence and other fields.
How did philosophy get this way? Russell's hypothesis is not too shabby. Check the syllabi of the undergraduate "intro to philosophy" classes at the world's top 5 U.S. philosophy departments — NYU, Rutgers, Princeton, Michigan Ann Arbor, and Harvard — and you'll find that they spend a lot of time with (1) old dead guys who were wrong about almost everything because they knew nothing of modern logic, probability theory, or science, and with (2) 20th century philosophers who were way too enamored with cogsci-ignorant armchair philosophy. (I say more about the reasons for philosophy's degenerate state here.)
As the CEO of a philosophy/math/compsci research institute, I think many philosophical problems are important. But the field of philosophy doesn't seem to be very good at answering them. What can we do?
Why, come up with better philosophical methods, of course!
Scientific methods have improved over time, and so can philosophical methods. Here is the first of my recommendations...
More Pearl and Kahneman, less Plato and Kant
Philosophical training should begin with the latest and greatest formal methods ("Pearl" for the probabilistic graphical models made famous in Pearl 1988), and the latest and greatest science ("Kahneman" for the science of human reasoning reviewed in Kahneman 2011). Beginning with Plato and Kant (and company), as most universities do today, both (1) filters for inexact thinkers, as Russell suggested, and (2) teaches people to have too much respect for failed philosophical methods that are out of touch with 20th century breakthroughs in math and science.
So, I recommend we teach young philosophy students:
(In other words: train philosophy students like they do at CMU, but even "more so.")
So, my own "intro to philosophy" mega-course might be guided by the following core readings:
(There are many prerequisites to these, of course. I think philosophy should be a Highly Advanced subject of study that requires lots of prior training in maths and the sciences, like string theory but hopefully more productive.)
Once students are equipped with some of the latest math and science, then let them tackle The Big Questions. I bet they'd get farther than those raised on Plato and Kant instead.
You might also let them read 20th century analytic philosophy at that point — hopefully their training will have inoculated them from picking up bad thinking habits.
