In recent memory, and a lot of people who would be considered knowledgable and intelligent (eg George Bernard Shaw, Alexander Graham Bell, Winston Churchill, HG Wells, Theodore Roosevelt) all considered Eugenics to be a danger to the modern world.
Several countries started sterilising people against their will - and in the UK a Private Members Bill was put before parliament to allow 'voluntary' sterilisation.
Now think what would happen if these countries had a DNA database.
Maybe we could euthanise people who were at risk from cancers or other diseases that cost the NHS money>
How about anyone who was at risk of being obese was also not allowed to live - after all, they are but a burden to society.
