Society is full of stereotypes and bigotry.
Bureaucracy defines how incapable people are to take care of themselves.
The Government determines how disabled someone is from to physical to mental health.
Not all institutions care for the people no matter how ill they are.
Not all heroes care for the disabled. Tear away the mask and what is left of humanity to care for incurable misfits who just want to live?
Mental illnesses aren't curable just full of treatments like medicines, therapies and doctors.
Psychotic breaks aren't curable just appeared to be crazy illusions of a mad person. Which they aren't always wrong just smarter than the average human sometimes.
