One of the problems with this understanding of heaven and hell is that we are only truly in communion with one another in heaven, not hell. Hell is, ultimately, the choice for self over God and over those made in God's image. Those in hell will not be enjoying communion with one another because their choice for self means that they have no capacity to love one another because they cannot truly love one another apart from God. Far better is that if one wants to be in communion with deceased loved ones that they hope they are in heaven and seek to join them there than to be willing to join them in hell. – from the Catholic Answers website (www.catholic.com)
