Mental illness is far more dangerous than physical illness, we need to think of correcting and reforming the moral vices before they take root in human. Khajeh Nasiroddin Tusi writes in his book by the name of Naseri ethical book: I read in a book qouted by one of the Greek philosophers that If a ship is caught in storms like mountains at sea, Saving this ship and its people is much easier than saving someone who is suffering from moral vices! It is easier than saving someone who is runing afoul of envy, egotism, anger, ego, and pelf.
