well she was definitely on the cusp of self awareness right before she died originally, which is part of what made her death so tragic. like we see in the afterlife, she is stuck in that arrested development of just barely getting it and then inevitably sinking into her old ways, and its been super implied that death means that your development as a person is bound to stagnate.
with the influence of the other kids on the meteor and with the freedom to actually maybe talk things out with terezi and actually grow up, i do think vriska could have improved? which doesnt mean that her victims should forgive her for the shit she did if they dont want to. (it’s nice that she brought tavros back but she should Leave Him Alone)
ultimately like, vriska did and said lot of horrible things but she was also a literal child and the tragedy was that she died before she got to do what all shit kids do, which is grow up and have the opportunity to learn from her mistakes. we’ll just have to wait and see how much she actually HAS learned or how much she stayed the same! time will tell.
