The Living Force
And you disprove your own point and original situation mentioning INSTINCT, that it is something that one does consciously. Instinct does not equal sacrifice. If you made the bad split second decision and your family suffered for it, would you be as holy?So you're on a nitpicking shtick now? If you see a person drowning in a river, you jump in when you make VERY quick assessment of the situation. There is NO thought for 'reward'.
It's still a calculation done by instinct. In fact, because it is instinct, the reward is easier- the LOW PATH of the brain takes over. Remember that part of the wave?
