Futurestan, the nation that deals with its problems by shooting them into space, has a serious problem. You see, their economy is largely dependent on industrial processes that, among other things, produce a lot of gaseous carbon waste. Normally this wouldn't be a problem, because they have extremely efficient methods of harvesting this carbon and converting it into a more socially conscious form of pollution.
Unfortunately, these "carbon harvesters (patent pending)" depend on a certain form of GMO potato and their neighbors to the north Other Different Futurestan own the patent for this potato's genome and have withdrawn shipment from Futurestan unless they amend the Treaty of the Before Times to exclude the article preventing Other Different Futurestan from changing its name to "Other Better Futurestan" (for the record Other Different Futurestan is objectively better than Futurestan). This situation threatens to escalate into war.
One of the ways that ODF is objectively better than Futurestan is its military might. You see they realized a long time ago that robots are simply better than humans at pretty much everything up to, and including, war so their entire military force is robotic. Futurestan, however, has a crippling fear of the robot apocalypse largely brought on by a state religion loosely based on the Matrix and Terminator trilogies and thus refuse to militarize robots.
Futurestan's solution is to create cloned super humans that can be quickly mass produced on the cheap. Then, to take it a step further, they remove these cloned super soldiers emotions via a process vaguely resembling sticking a hot wire in their brains and jiggling it around. The original plan was to remove all of their emotions, but after they lost their entire standing army to mass suicide, they decided on a new plan.
THE PLAN: Remove the minimum amount of emotions (one) from each of their super soldiers.
THE QUESTION: What happens when they execute said plan? Specifically what would be the best emotion to remove to create super soldiers? What are the consequences on said super soldiers?
BONUS POINTS: Would removing different emotions be better for different military positions and how and which ones? How would "compound" emotions work?
- The removed emotion is one of the basic emotions of anger, disgust, fear, happiness, sadness, or surprise.
- Other than removing the emotion nothing else is done to their brain after "birth".
- This process does not damage the brain any more than described.
- The super soldiers are basically created to be physically and mentally the best at whatever their military role (Enhanced reaction time/strength/senses/etc.), but not necessarily good at anything else.
- The brain works in a way that allows you to fry one emotion without damaging the others.
