Who lie under the curse of the law of Moses? [2nd of 3 questions on this topic]

Who did it apply to in the time of Moses, then in the time of Christ what did Paul say about Gentiles also being cursed in their rebellion (disobedience)? (e.g. Romans 1:18-23 & 2:14-15 & 3:9). Does this mean that the curse rested not only upon the Jews, who had the written law, but also on all men seeking acceptance with God through works of law-keeping? ***The 3rd question in this series asks about [what the consequences of the curse are](https://christianity.stackexchange.com/q/107550/10672).*** This question is scoped for any Christians who believe perfect obedience to God’s laws are the goal all Christians should, and could, aspire to, to be justified; but as there may be very few such individuals on this site, to also seek answers from those who say such a thing is impossible, but that there are aspects of God’s law Christians must follow, albeit not with salvation in view, but to please and honour him.
