I just saw this in the comments as well, also spoiler!!
In this life, mc's revenge is not to kill her family bc she had alrdy done that in her prev life and it was not 'satsifying'. Her ultimate goal in this life is to actually just die. Like die without being reincarnated. She has no ounce of care for her family whatsoever. But someone else pointed out that her 'revenge' for this life (whether she's doing it knowingly or unknowingly) is to make the family lose power and control (something that they relied on heavily and used against her) and make them feel powerless just like how she felt powerless in her previous life because of them which i think is a much better revenge plot (๑•ㅂ•)و✧

Revenge is nice. But I'd rather read an MC striving towards her happiness rather than fighting to death for revenge. Sometimes, ignoring your enemy is (in a way) can be counted as revenge.
