It must be said, different perspectives yield entirely different conclusions on the same issue.
When Jiang Liu watched "Journey to the West" in his previous life, he always thought Princess Wansheng and the Nine-Headed Serpent were villains. After all, being married and yet colluding with another man seemed quite evil to him.
Therefore, in the original story, he almost wished the White Dragon Horse could kill both Princess Wansheng and the Nine-Headed Serpent.
But, standing in Benboba's shoes, he felt that the White Dragon Horse was the villain.
From Benboba's point of view, Princess Wansheng and the Nine-Headed Serpent were deeply in love, even privately committed to each other for life. Yet, Little White Dragon wanted to forcefully take that love for himself, which made him the villain in Benboba's eyes.
