the mistakes of the mother and the father live on and on
3 children who did not make the choices their mother and father made, but paid for their mistakes regardless. they didn't make the choice to be half-breeds. they didn't make the choice to have retarded, sub-90iq parents. they did not make the choices but they died.
there probably should be laws against doing what these parents did. it should be illegal for them to have children together.
