Which are "eternal" destinations according to roman catholicism?

Answer - Paradise; Hell

Eternal destinations, according to Roman Catholicism, refer to paradise and hell. The Church affirms that after death, the souls of those who die in a state of mortal sin immediately descend into hell, where they will suffer the punishment of hell's eternal fire, while all who die in God's grace and friendship will go to paradise, but those who are not yet perfectly purified will first go to purgatory before entering paradise.
