If you don't code a comparison, no comparison will be made by the computer. You see a comparitive function where there is none, seems simple.
Other then equation comparisons, there might be real comparisons in the random function of the computer. If it is true that the randomizer in the event could turn out one way or another, then there might be a real comparison between options, as part of the determination between one or the other option. But what those options actually consist of I don't know, and I think the computer randomizer is mostly chaotic working from registers (predetermined) in stead of chancy (indeterminate). So basically only in chance can I see any reality for comparison, and the comparison in Natural Selection has no basis in reality.
