technically we still dont know what happened 4-6th life. we dont know if 7th was the start and i suspect it wasnt, since she had enough ambition to actually kill them. again, all speculation and i personally think she started turning around 4th life (and you have to remember all of the trauma she went through for each. and every. one of those damned lives, it makes sense she craved attention so much)

I've yet to read all the chapters but even if she thinks like that I can't wrap my head around how could someone self blame for that many life times before realizing that it's not her but them. I mean if someone is treating you like trash more than you can count I bet it's not about the choices you make but rather that person being the trash.

it was just an estimation from my speculations, since she decided to be more wary of her family her second life and learned not to trust christian in her next/3rd life. during her third life she mightve just started living sort of how she always wanted to a little bit. 4th life she may have started experimenting out of her immediate circle (like the calicia boy), 5th probably would have be a more experienced version of her last and also learning how to get stronger, her 6th might have been when she started to learn how to build up her powers more, and her 7th when she finally gets revenge on her family. this is probably inaccurate as hell but these are my guesses for what she has done with her lives so far
It took f*cking 7 life times to realize that her family was trash, she is not the brightest of the bunch, ain't she ? -.-
