For those of you who haven't played Starcraft, you have something called a probe. It's a robot, and you use it to get money. If the enemy kills a lot of probes, you don't get a lot of money, and you're in big trouble. So you need to protect your probes, even if it means sacrificing some units to get rid of the threat.
Now, probes are used by a race called the Protoss. The protoss fight honorably in battle and are willing to do anything--even die--to protect their people (or reptiles I should say.) So what happens? Probes are vital to getting lots of money, so...
The protoss sacrifice themselves for ROBOTS! Instead of saving each other, they protect robots without souls. How many human beings would give up their lives for a machine? We sacrifice ourselves to save other human beings, which is a strength. But if our remote-controlled tanks were in trouble, I think some people would save another human being rather than protect the tanks. But the protoss--they die and lose loved ones so that robots can keep getting money.
How ironic...or should I say, honorable...
