Sure I do, however, the premise would be substantially more honest if "family" weren't invoked. Why not say for the good of future humankind/humanity? What really is the difference between family 3 generations in the future vs 3 generations past? Genetically we are all related, yet we kill our neighbors for profit/envy/power. They are our relatives as well. Shouldn't we have the same loyalty and concern about the progeny from our great grandfather's brother's/sister's line? Invoking familial vanity as a means of improving the future doesn't really improve the future.
