Maybe.
Or did he fulfill the law when he stood in the place of others to suffer the punishment the law requires for their sins?
Exactly. You see, when I am judged by God I will be shown as unrighteous because of my failure to uphold the
entirety of the Law. However, though I may beg for mercy I am confident that Jesus, who never broke the Law, is righteous for me. My crappy record is thrown in the trash, and His righteousness is put on my record because He makes me clean. I trust Him in that.
Thus, Jesus fulfilled the Law and we "died to the Law" (Romans 7:4).
The reason I brought up this stuff about Angels is that Paul and the author of Hebrews makes a very specific argument: that the Law was mediated through an inferior agent (angel) while the New Covenant is continually mediated by God Himself at all times (the Holy Spirit in us, Christ's intercession with the Father, and the Father's I suppose implicit forgiveness and sending the Holy Spirit.)
If you read the OT, you realize the ten commandments and revelations (i.e. Ezekiel's) came by an Angel of the Lord, whom the prophet addressed as the Lord. Sort of like a King using a messenger and the messenger tells you the King's decree. In response, we might tell the messenger our response, even addressing the messenger as the King.
