‘You would do evil to produce good?’ asked Mr. Booker ‘I do not call it doing evil. you have to destroy a thousand living things every time you take a glass of water, but you do not think of that when you are athirst.

You tell me this man may perhaps ruin hundreds, but then again he may create a new world in which millions will be rich and happy.’
