Packs of wolves do automatically specialize their individuals (eg alpha wolf spends more time looking after the others) - but the crucial part is that their roles change. If the alpha dies, another individual has to take their place, or the group becomes unbalanced and will probably die because of it. They are not necessarily „gifted“ at being an alpha, but they might be just good enough.
I also cannot imagine helping anybody move who laughed into my face when it was my turn. I actually cannot imagine being their friend at all, but that’s just me maybe.
