I am not sure I agree with this statement. It is easy to condemn British imperialism, although rather hard to pin down what and when British Imperialism was. During a long period, the nearest thing to a British policy of Imperialism was its naval, and occasionally military campaign against slavery which at one point consimed as much as 5% of GDP. I would not characterise that as evil. For a good bit of the 19th century it was actually rather hard to get into the British Empire and a number of states were turned down when they applied. The scramble for Africa was a rather unprepossessing, although short period during which at least one territory asked for direct rulecby the empire for fear of being absorbed by South Africa. Much of the Mddle Eastern territories were never part of the empire- they were mandates given by an international organisation. Egypt was in fact a white knight bailout.
Evil? Good? A mixture, with far more shades of grey than most empires in history.
