When Brian realized that he himself was a Mutant and that there was no such thing as a Golden Finger, his feelings were very complex.
According to Susan's claims,
Mutants are either super-perverts or mentally ill.
These people, after being exposed to the radiation of the Blood Moon, had a certain probability of receiving the Blood Moon Gift.
The Gift's power would reflect the host's heart, giving birth to the ability that the host most desired and was most compatible with, and with the passage of time, the dark side of their hearts would uncontrollably surface, gradually losing sanity and committing crimes.
According to Susan's words,
Once these Mutants acted on their inner darkness, and their desires were satisfied, they would become stronger while their sanity diminished even further.
