The feeling of schadenfreude stems from the belief that she is a false prophet. She fervently condemned every minor, and in the case of the Tories, major, wrongdoing with the zeal of a puritanical preacher, presenting herself as pure and untainted by the greed, gluttony, and self-serving sins of the middle and upper classes. Ange was seen as a person on our side, standing against this entitled establishment.
We initially gave her the benefit of the doubt regarding her pre-government house-flipping, thinking, "I would do that, too." However, as the second-most important person in government, it took her less than a year to join the very ranks of the people she had so passionately condemned.
Her actions validated the quiet guilt felt by a son of a Llanedeyrn single parent who, after drifting away from the Labour Party for decades, wants to keep the money he worked and sacrificed so hard for to ensure his children and their children don't have to grow up like he did. Raynor's behavior simply confirmed that even the "purest" of people can succumb to this and she is a bit of a fraud.
