It just baffles me that people defend Dooku's morality so often when the dude is so evil. It's like, is the guy really so charismatic that people are willing to look beyond him being sadistic and committing genocide and killing countless innocents and shit like that to try and justify his morality?
For all of Maul's demonic appearance and Dooku's charisma, Dooku is actually more vile than Maul is tbh
In the DR novel Ventress apparently used her feminine whiles on Dooku in an attempt to get him to teach him more Sith knowledge which Dooku is described as being "not adverse to." And then later he just leaves her sprawled on the floor by cutting off circulation to her brain or something of the sort and they both don't look at eachother after not willing to acknowledge the moment before parting ways.
It suggests abuse not only on an emotional or physical level but a sexual one as well. That just might be my own imaginings though.
