@Paro 1st of all Shannet left the family in the original time line due to her husband betrayal so if the empress was in the Lombardi in the original timeline Shannet couldn't compete with her and tia had no intention of being matriarch back then that would leave the empress as matriarch by default now i am not saying she would be better then the tia or Shannet but she would of at least been good enough to avoid the destruction of the Lombardi preventing the regression
2nd if she was in the Lombardi there is a few hints that she would be different the Lombardi are very family oriented and out of all the Lombardi we have seen the only "bad eggs" is tias uncle and his kid and the one who hangs around him (all of whom are also connected to the empress family) so while I can't guarantee she would be less selfish it is at the very least a real possibility
