Who seems to sarcastically reference the perception of wrongness in others?

The character who sarcastically references the perception of wrongness in others is indeed Vincent. Throughout the narrative, Vincent often deals with the societal expectations placed on individuals based on their genetic make-up. His perspective reflects a deep understanding of how prejudices can influence how people view each other, particularly in a world that prioritizes genetic perfection.

Vincent's sarcasm serves as a coping mechanism and highlights his awareness of the flawed reasoning behind judging individuals based on their genetic identity. By making sarcastic remarks, he underscores the absurdity of a system that deems people as inferior or flawed based solely on inherent traits they were born with, rather than their capabilities or personal choices. This provides a powerful commentary on the larger themes of identity and discrimination within the film.

Jerome, Irene, and the Director, while also central to the story, do not exhibit this same level of sarcastic commentary regarding the perception of wrongness in others. Each of them is portrayed in different contexts that focus more on their personal struggles and the impact of societal expectations, rather than through a lens of sarcasm.
