At first I thought you were simply going to rationalize your position by providing possible selfish motivations for events that seem to be sacrifices, but then realized that you are foisting on us an untestable and unfalsifiable claim; namely, 'All subconcious decisions benefit the organism'.
Let's assume we could agree on a non-mortal event that qualifies as a sacrifice as generally understood by the term. Let's further imagine that the sacrificer tells us that he/she performed the act for unselfish reasons. Your only play at this point is to claim that this is a rationalization of the sacrificer's conscious, but in reality the sacrificer's subconcioius made the decision based on a benefit that you get to dictate.
You should probably give this more consideration.
