But, for all his faults, Londo always had the good of Centauri & "taking them back to the stars". He always had that forefront in his goals/agendas. & if those ideals coincided with his personal quset for power, so be it.
But I loved Londo's character development & I can't think of another actor who could've come close to this feat.
I remember thinking when he went into the Council Chambers after the bombing of Narn & he insisted that G'Kar be removed from the Council. For all his screaming & demanding, you could see he was afraid & full of self loathing over what he had done, or helped put into motion. Such complexities in one character. Gotta love Londo.
