Well, whatever her crimes, we know what the sentence will be. She'll be sentenced to 6 months of rehabilitative therapy, maybe in conjunction with "hard" labor in the New Zealand penal colony. Then she'll probably be returned to society as a productive member again. Maybe she'll even want to go back to her colony near the wormhole and help introduce the latest technological innovations to her former followers.
Garak only got six months for attempted genocide along with a slew of assault/sabotage charges. By all accounts he got out early too.
Kassidy got six months to a year for smuggling for terrorists.
Paris was an actual member of a terrorist group and literally got out of jail free. Even in the alternate future where he didn't go to the Delta Quadrant he was out of jail in a few months.
The Federation penal system is ridiculously nice. Alixius probably would be out of jail in a few months.
