The thing is, as I realised on this re-reading, that Milady does not actually commit all that many crimes on the pages of the book. We are told her previous crimes by unbearably entitled, self-righteous men who want revenge; the chapter where they sit "trial" over her is actually really disgusting. The men are unbearable.

Oddly, all adaptations tend to go the "cheeky chappies" route, leaving out all the interesting, dark stuff! These characters have the potential to be much more interesting and multi-layered than they are presented in the films and than they have imprinted themselves on the readers'/audience's hive mind.
