To enter heaven is to become more human than you ever succeeded in being on earth
 to enter hell is to be banished from humanity. What is cast (or casts itself) into hell is not a man: it is “remains.” To be a complete man means to have the passions obedient to the will and the will offered to God: to have been a man – to be an ex-man or “damned ghost” – would presumably mean to consist of a will utterly centered in its self and passions utterly uncontrolled by the will.
