This brief description has much more to the story, and I would like to add my perspective.
Kitchener (later Lord Kitchener) was considered a war hero.
The city where I live was once called Berlin, because of the large number of German background who had settled here. It was (still is) a thriving industrious town. During WW1 goods that were manufactured here were marked "Made in Berlin", but, as Canada was at war with Germany, there was considerable resentment for buying goods with any association with negative connotations.
It was decided that a name change was needed to re-brand the city, and, in honour of the great hero, the name "Kitchener" was chosen, with some controversy.
These days, with revisionist historians running amok, we can acknowledge that the great Kitchener was also responsible (along with Winston Churchill) for creating what we now consider the development of concentration camps during the Boer War.
After the Battle of Omdurman, the British went about completing the slaughter (along with Winston Churchill) of the wounded soldiers, as there was no way to attend to them medically and therefore "putting them out of their misery" was considered humane.
