Rodolphus was going to pay for his meddling. Maybe Antonin was right and they would never be able to figure out his true motivations for placing a network of memory charms in her mind. She knew that she would just drive herself mad if she tried to figure it out. But, that didn't mean she wasn't going to get her revenge. What Rodolphus did to her was inhumane and very cruel. How much of her life could've been different if he hadn't bothered her? Of course, dwelling on "what-ifs" was just as damaging. Somehow she would need to learn how to move forward and ignore the regrets.
