The short answer is “Yes.”
The long answer is “Yes” – with the qualification that “making it” doesn’t mean everyone just walks freely into the kingdom in their sinful state. Jesus says in John 3: “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” Nothing unclean comes into the kingdom.
Or as Paul says in Galatians 5: "Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ Jesus have crucified the flesh with its passions and desires."
The child rapist must have truly repented – as all of us must truly repent – before he can enter the kingdom of God. Paul writes in Colossians 3: “Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. On account of these the wrath of God is coming. In these you too once walked, when you were living in them. But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth.” The sinful self must die and the person be raised up a new creature, born into the life of Christ.
If we say that some people are so bad, their deeds so evil, they should not be saved – what are we really saying? We are implying that we deserve mercy and grace, but those people over there don’t. Then we become the Pharisee who prayed, “God, I thank you that I am not like other men, extortioners, unjust, adulterers, or even like this tax collector.”
The more evil a person is, the more they desperately need to be saved – rescued from their sin, and made righteous. Jesus says there is rejoicing in heaven over a sinner who repents, and that the one who is forgiven much, loves much. The more evil a person is, the more we should rejoice when he repents – it’s not because we are glad that he won’t be punished, we are glad that he has renounced evil and wants to do right – our brother was dead, and now he is alive.
To take a slightly different angle. As long as sin is existing in any person, God is not his Master. Paul teaches in Romans 6 that our Master is whoever we are obedient to. The last enemy to be destroyed is death (which comes from sin), and every knee will bow, and every tongue swear allegiance to God.
When Jesus dined with the tax collector, Zacchaeus, the Pharisees complained that Jesus was being the guest of a sinner. Then … “Zacchaeus stood and said to the Lord, ‘Behold, Lord, the half of my goods I give to the poor. And if I have defrauded anyone of anything, I restore it fourfold.’ And Jesus said to him, ‘Today salvation has come to this house, since he also is a son of Abraham. For the Son of Man came to seek and to save the lost.’”
Basically the same answer as others have given, just had to throw in my two cents as well!
Hope that helps,
