Maybe how you see it depends on if you think Jesus is God.
As man, Jesus retained all His Godly attributes and identity, but laid aside all His power and became fully man, living by faith, relying wholly on His Father for all things, dependant on HIs Father's strength just as we must rely on Christ's strength.
As for Jesus having the potential for sin. Yes, if He had sinned, all would have been lost. Everything. So not just man would have been eternally bereft of a Saviour, but God Himself would have lost His Son. The Son wrapped Himself within humanity on an eternal basis. He didn't temporarily become man and revert to being God. If He had failed, there was no plan B that would see Him return to heaven and continue as if nothing happened. There was always a massive risk ...which brings more glory to the Godhead that such a covenant would be made and such a risk taken. God
did indeed love the world so much that He gave His own Son to the human race. When scripture says the Son became flesh, it means it. Not just physical flesh and blood, but flesh as in carnal natural man. Fully capable of sin. Only without the propensities that man is born with. But throughout His life it was a constant struggle to fight temptation and to successfully carry out His mission...to present Himself a sacrifice, holy and acceptable unto God.
At any time He could have returned to heaven and said, 'nah, people ain't worth the bother". But He would have been the only human being to be in glory. He thought heaven without us, was not worth grasping even at the cost of Himself.
―Forasmuch then as the children are partakers of flesh and blood, he [Jesus] also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; And deliver them who through fear of death were all their lifetime subject to bondage. For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people. For in that he himself hath suffered being tempted, he is able to succour them that are tempted.‖ Hebrews 2:14 18
―Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. For we have not an high priest which cannot be touched with the feeling of our infirmities;
but was in all points tempted like as we are, yet without sin. Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.‖ Hebrews 4:14-16
Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and
was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.‖ Philippians 2:5 -8
When Christ became our substitute and surety, it was as a human being. He came as a man, and rendered the obedience of human nature to the only true God. He came not to show us what God could do, but what God did do, and what man, a partaker of the divine nature, can do. It was the human nature of Christ that endured the temptations in the wilderness, not His divine nature. In His human nature He endured the contradiction of sinners against Himself. He lived a perfect human life. Jesus is everything to us, and He says to us, "Without Me ye can do nothing." Many claim that it was impossible for Christ to be overcome by temptation. Then He could not have been placed in Adam’s position; He could not have gained the victory that Adam failed to gain. If we have in any sense a more trying conflict than had Christ, then He would not be able to succor us. But our Saviour took humanity, with all its liabilities. He took the nature of man, with the possibility of yielding to temptation. We have nothing to bear which He has not endured.
