Seriously, I really don't understand why some Villains can't have different mental illnesses on the Villains wiki rather than just Posttraumatic stress disorder, Dissociative identity disorder, Schizophrenia and psychosis unlike on The Heroes Wiki.
Why can't they have other mental disorders and illnesses such as depression, amnesia and anxiety for examples as well?
Plus, not all villains need to have horrible behaviours, beliefs or actions to be mentally ill. They can have different mental disorders and illnesses as well.
