Lately I have a persistent and vague memory of a scene, maybe from an anime, which I cannot even contextualize, which I watched not so long ago. It is very probably about revenge and human-to-animal transmutation.
The scene I remember is the following: there is a big, splendid palace (kind of liberty-styled), in which some rich people, maybe nobles, are having a ball/banquet. Suddenly a curtain drops(?) and many wild animals appear, making the viewer to realize that they were humans not so long ago. I have the sensation that the nobles / rich people themselves were transformed into animals in order to enact a revenge against their evil behavior in a kind of ironic way. The palace is finally seen from the distance, set to fire, in a final act of grace.
