> Probably many more died because of the British Empire's policies
I don't think body counts are a useful indicator of the level of evil intent of a government or a regime.
On that basis the U.S. would fare significantly worse than Nazi Germany, based on the 10-16 million killed as a result of U.S. foreign policy since 1945 alone (see http://nottheenemy.com/index_files/Death%20Counts/Death%20Co...)
It would take a crackpot to declare the U.S more "evil" than Nazi Germany.
> The benefits that you mentioned was[sic] simply benefits of an industrial society
Not true.
China is increasingly a heavily industrialised society yet still maintains an autocratic system of government with no democracy. It doesn't follow that just because a society embraces industrialisation it implements a fair system of government or invests heavily in infrastructure programs - just look at the crumbling roads and transport in North Korea alongside their hi-tech nuclear ambitions.
> The general population in the victim countries did not share in the advantages of it
To quote Manmohan Singh (the current Prime Minister of India):
"Today, with the balance and perspective offered by the passage of time and the benefit of hindsight, it is possible for an Indian Prime Minister to assert that India's experience with Britain had its beneficial consequences too. Our notions of the rule of law, of a Constitutional government, of a free press, of a professional civil service, of modern universities and research laboratories have all been fashioned in the crucible where an age old civilisation met the dominant Empire of the day."

> Probably the worst thing that the British Empire did was large scale ethnocide
This is undeniable, and indefensible. However, unlike Nazi Germany it appears this wasn't the Raison d'être for the empire.
> People in Britain still live with the mindset that colonialism and their colonial empire was a good thing.
Not true. I don't know what evidence you are basing this opinion on, but the brutal effects of Colonialism are taught throughout the British national school curriculum and in various British museums. No punches are pulled.
