Hume was very outspoken and never feared to criticise when he thought the Government was in the wrong. Even in 1861, he objected to the concentration of police and judicial functions in the hands of police superintendents. In March 1861, he took a medical leave due to a breakdown from overwork and departed for Britain. Before leaving, he condemned the flogging and punitive measures initiated by the provincial government as 'barbarous ... torture'. He was allowed to return to Etawah only after apologising for the tone of his criticism. He criticised the administration of Lord Lytton before 1879 which according to him, had cared little for the welfare and aspiration of the people of India.
