It is difficult to say which one race of people would have the most positive effect on society if all were to be killed at once, as the impact of such a situation would be immense and difficult to estimate. Depending on the size and makeup of the society in question, it is likely that the loss of any race would create ripple effects which would be felt across other areas of society.
