According to John 3:18, the only reason "some men are under condemnation" is because they have not believed in the Lord Jesus Christ.
John 3:17-18 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

18 Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
They didnt have to believe to receive Justified to life, the Justification of life was the result of what Christ did for them before they were born
Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one Man’s righteous act the free gift came to all men, resulting in justification of life.NKJV
