Major comment on this from me is that its a very euro-centric list.
Anyway, would like to suggest that Athenian Democracry be taken off the list as in the large scale of things that was a very minor empire over a handful of Greek speaking coastal villages. The Persian (Achaemenids) meanwhile managed quite a bit of expansion in that century by bringing some dependent states directly under their rule and re-established control over many territories lost to rebellions.
Pope Urban II is surely the real bad boy of the 11th century
Some other debatable alternatives
Simon Bolivar / Shaka Zulu - 19th century
Various Norman invasions - 11th century
Aztecs killed a lot of people in 16th century, Spain just sneezed in the wrong places
Maybe consider replacing Hitler with Stalin (or even Mao?) for 20th century as he has more souls trailing in his wake.
