RE: Did not Jesus carry the sin of all humanity, past present future?
Yes.
†. Isa 53:6 . . Yhvh has laid on him the iniquity of us all.
†. John 3:16-17 . . God so cared for the world, that He donated His only begotten son, that whosoever believes in him should not perish, but have everlasting life. For God sent not His son into the world to condemn the world; but that the world through him might be spared.
†. 1Tim 2:6 . .Who gave himself a ransom for all
†. 1Tim 4:10 . .We trust in the living God, who is the savior of all men
†. 1John 2:2 . . He himself is the propitiation for our sins, and not for ours only but also for the whole world.
RE: Can we say, Jesus paid for this man's sin, but if he does not believe, it will still be on his back?
Yes, you can say that.
†. Mrk 16:15-16 . . And he said unto them: Go into all the world, and preach the gospel everywhere to everybody. He that believes and is baptized shall be spared; but he that disbelieves shall be damned.
†. John 3:18 . . Whoever believes on him is not condemned: but he that disbelieves is condemned already
†. John 3:36 . . Whoever believes on the Son has eternal life: but the individual that disbelieves the Son shall not see life; but the wrath of God abides on him.
†. John 8:24 . . If you disbelieve that I am he, you shall die in your sins.
RE: Would this not be like saying what Jesus did was not all sufficient?
He's all-sufficient for believers, while totally useless to disbelievers.
†. John 5:24 . . I assure you, those who heed my message, and trust in God who sent me, have eternal life. They will never be condemned for their sins, but they have already passed from Death into Life.
†. Rev 21:8 . . Unbelievers shall have their part in the lake that burns with fire and sulfur. This is the second death.
RE: then there is only one conclusion: People go to hell for rejecting Jesus
It isn't necessary to reject Jesus in order to go to Hell; and that's because Hell isn't optional; no, Hell is the default.
There's an incident in Num 21:5-9 where Yhvh's people got to complaining about the quality of food that God was supplying for their daily needs. As retribution for their insolence and shameful ingratitude, the Lord sent a swarm of deadly poisonous reptiles into camp. Everyone bitten by them instantly became a dead-man-walking because the venom was 100% fatal, no exceptions. When the people realized their blunder, they begged Moses to intercede for them and the Lord instructed Moses to construct an effigy of the reptiles and hoist it up on a pole where everybody could see it. Those who looked at the effigy were cured; those who didn't of course died.
Jesus likened the necessity of his crucifixion to that very incident. In other words, had not Christ been crucified; absolutely nobody would go to heaven because everybody is, without exception, a dead man walking.
†. John 3:14-15 . . Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, that everyone who believes in him may have eternal life.
†. Eph 2:1-5 . . As for you, you were dead in your transgressions and sins, and were by nature, objects of wrath. But because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions
RE: Could this be the blasphemy against the Holy Spirit (since the Holy Spirit testifies for Jesus), the ONLY sin that can not be forgiven?
The Greek word for blasphemy is blasphemia (blas-fay-me'-ah) which means: vilification; which Webster's defines as: a defamatory utterance: e.g. slander, unfounded allegations, and/or malicious gossip.
In context (Mtt 12:24-32) the blasphemy about which Jesus spoke is an accusation that Christ is a member of a satanic cult.
RE: trampling Him underfoot.
It isn't necessary to write Jesus off as a member of a satanic cult in order to qualify for the retribution described at Heb 10:26-31. It's only necessary that upon hearing of Jesus' crucifixion, one blow off his death as little more worthy of their attention than that of a common man.
