@Tusk @JaeBae she altered their pasts to remove their present as she observed it from existence; she essentially made an alternate timeline for their lives and overlaid it onto the present timeline. Thus, she rewrote history. You might think it's awesome, but imagine if she did that for someone like Hitler. The butterfly effect from such an action would likely have huge ramifications on the entire progression of history from that point onwards, and that might not be a good thing.
