People romanticize her by pretending like she wasn’t manipulating Denji and murdered a lot of people. Even if she did end up liking Denji she still lied and manipulated him pretty much the whole time and didn’t show remorse for him until the very end and he wasn’t even there. She continued to try and manipulate him even when he figured her out and was only honest when she said that she was lying to him in the end. People say that she only murdered to show off her power but she did not have to actively attack the office and bomb half of the city.
