The Relationship with her two children is vague but presumably not abusive. In her very first appearence she seems to be taunting Ambosius but this could have also been of a jokingly, playfull nature. Despite her perverted nature she seems to activly care about her son (as seen in page 54) even if by the end of it the page she has taken nude picturess of him.
Cassandra seems to work for the military like her son, although on a much lower rank. In chapter 3 (which is mostly a prequel to chapter 1) she seems to (Judging from her appearence) have the rank of a recuit or common soldier while in chapter 1 she appears to posses a much higher rank (most likely some form of officer)
~Cassandra commits various crimes in the comics ranging from the possesion of child pornography over incest to mutilation and assault
Cassandra seems to be a self insert character of the comic-author as we can deduct from her sexual prefrences and name
