What evil did Gandhi describe as the main point of the letter?

Explanation:

Ghandi wants his countrymen to understand the difference between the British and  British imperialism. He also claims that the hatred his countymen feel will make them fall into a new state of slavery since they will think that Japan is different from Britain. Not feeling hatred is the solution to India’s problems. In fact, they have been able to ask Britain to withdraw because of India’s due part in the critical juncture ; not because of her anger. Ghandi himself does not feel any hatred towards the British or anybody else, even when he is undergoing the most critical moment in his life.
