Rom 5:18
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.
No by no means does Rom 5:18 teach that Christ died for all without exception, just because the word all is used. In fact, to the spiritually discerning it teaches the contrary, it teaches the limited atonement, or that Christ did not die for all men without exception, simply because the all men here that Justification of life came upon is limited to only some men, so the word all can only apply to all that received upon them Justification of life.
For its clear from other scripture that all men without exception are Justified before God, for instance Matt 5:45
45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
Acts 24:15
And have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust.
1 Cor 6:1
Dare any of you, having a matter against another, go to law before the unjust, and not before the saints?
2 Pet 2:9
9 The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
Rev 22:11
11 He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
Now the word unjust does mean being found guilty before God, in Gods court of law,
describes being found guilty in God's court of law, i.e. as a binding, legal infraction against His law which calls for divine retribution,
unjust, unrighteous, wicked.of one who breaks God's laws, unrighteous, sinful,
So basically its one God reckons guilty before Him as a law beaker.
