For better or for worse our species is varied and specialized. Making sure to be humane and lenient as possible caring for the other parts of the community aside from the family is important. A village is stronger with different specialized groups of people. The blacksmith family, the knight warriors, the efficient farmers, the aesthetic artists, the builders, etc...
Hope that makes sense. A single family line cannot do everything. But it is important that each of those families to want the best for each of their own kids first so we can trust that their line continues and they will be benefiting the community as a whole too.

It's the same idea as an airplane emergency where you have to place the oxygen mask to yourself first then you can help the others around you put their oxygen mask.
