I think point out how group behavior in some animal groups look by keeping the weakest in the front they are preserving the numbers of the group and if something attacks them in front or trapped only the weakest ones get sacrificed. Shows they aren't dumb animals having logic to what they do.So what exactly are you asking our opinion about?
Do we agree with this hierarchy?
Is something about to happen and as the Alpha we decide who lives and who dies?
Or what do we we think of this in relation to human society?
Or all of the above and more?
