I wonder why we should worry about this. After all, as Jesus said, we are all evil (since God alone is good - Matt 19.17, Mk 10.18; Lk 18.19). Besides, who was it that said that it is to judge something or someone for ourselves?
Not to mention that Jesus was clear: we must love even the enemies (Matt 5:44,45). Therefore, it does not matter what the individual is or ceases to be. Since nothing happens by chance, therefore it was Jesus who brought them to us and it is up to us to open the door of our heart to them and love them, trusting that Jesus will not allow anything contaminated, impure or committing abomination and lies go in to us.
