Jesus christ sacrificed for humanity through his death according to bible. Means results and actions of people , taken by jesus till the end of the world. If this agrees what importance about final judgement. Because no one responsible their own actions, it have already taken by jesus-

I think this is meant to be interpreted that the actions we make in our lives will be forgiven, if we are faithful, and we will be able to enter eternal glory because Jesus died for us. He died to open the kingdom of heaven, so that souls would never be trapped in limbo again.

Accurately, the Bible says: For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. John 3:16-(emphasis added by me)
Man is still responsible for his/her actions. Jesus died for us while we were still sinners. When someone confesses & humbles themselves to admit they are a sinner and ask for that forgiveness- and they accept that Jesus died for them(&their sins) and they ask Jesus in their heart & with their mouth(if they can speak) to be Lord of their life---then they are saved- Born again, a new creature.
Now they are no longer a slave to sinning. The Holy Spirit/Jesus lives now in their heart.
If they sin, they have an advocate with the Father, Jesus, who now lives in them, and they can ask for forgiveness this way.
Those who do not accept God's Son remain in their sin. It's this sin that separates them from God.
Free will remains even for the Christian. All are responsible for their own actions(unless mentally ill)
The Great White thrown of Judgment is where the "goats" get separated from the "sheep"
The believers from the unbelievers.
The judgment for Christians is not whether they go to Paradise(they do) but it is about the "works" they did upon being a Christian that will determine how they will be honored in Heaven.
How shall we escape if we neglect so great a salvation?(Hebrews 2:3)

The responses you received are right. Not all sin is covered by Jesus sacrifice. Only sin based on imperfection due to our tendency to sin or sin done in ignorance because of being misinformed, uninformed, or being mentally incapable of comprehension. In contrast, sin practiced willfully and in full knowledge and understanding of Jesus' sacrifice might not be covered. But of course that judgement call in any specific case we should wisely leave to God. Psalm 75:7 Luke 23: 34


BTW

The final judgment in itself indicates that we are responsible for our actions and that our actions do have consequences in reference to our future.
