Not sure whether Winston Churchill was a monster however I can tell you on a unrelated incident which involves literature on Winston Churchill during WWII.
During one of my visits to HM establishment I here in England for a punch up and subsequent damage of someone’s personal property, I was placed in a segregation wing on good order and discipline for damaging government property, the item in question being a book in which Winston Churchill reintroduced the old colonial method of issuing identity cards for non English natives of one of the countries in the African continent, on see this I exploded and defaced the book, I was adjudicated and place in a polit cell ( a cell with nothing at all in it, no books, no nothing not even a blanket ) until I saw the nature of my error, my response to the governor when asked why I defaced the book was that I disliked colonialism, after being released some nine days later onto normal location I went back to read the book, having calmed down and had my wage reduced for a fortnight to pay for the book, I found out that the reason Winston Churchill reintroduced identity cards to the natives of the country was to help reduce the attempt of the Nazi’s marching in through the back door of the country, had he not instigated this identity card program the country may well have been overran with fifth columnists and subsequently the British and allied forces could have lost the country to the Nazi’s giving them a well needed strong hold which could have well cost field Marshall Montgomery to lose the battle against the desert fox Rommel, a true and interesting fact, at least I think so? (the African continent is very large so it is not worth assuming which country I am talking about?
