It doesn't say human nature or sin nature, what is says is
he had to be made like his brothers in every respect Heb 2:17, or as the AV puts it '
in all things it behoved him'. If the human nature we have is a sin nature and Jesus didn't have the same nature then he could not redeem us.
I'm sorry but the Bible version you are using is too liberal a translation for me to accept the "in every respect" clause. Jesus did not have the sin nature and we do.
I think Satan probably had better theology than you there and understood Jesus was as fully human as the rest of us

The Holy Spirit too who led him into the wilderness
to be tempted.
No I don't think so, Christ was incapable of sin, my theology is fine thanx. Being fully man and fully God does not mean he was capable of sin. The temptations were not a test but rather an example.
Heb 4:15 For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin.
I am afraid that is a bright idea some people thought up, that isn't in the bible, to explain why Jesus didn't inherits the sin nature that isn't mentioned in the bible, or why he wasn't born with Original Sin that isn't mentioned either.
I think it is useful to glean the expertise of doctrinal end theological meanings from experts and scholars even if it is extra-biblical. After all some of us use commentaries and studies in language to arrive at conclusions that are not necessarily explained in the Bible.
It is worth looking at the previous verse in Hebrews.
Heb 2:16 For surely it is not angels that he helps, but he helps the offspring of Abraham.
17 Therefore he had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people.
If the key to Jesus' nature was not having the sin nature passed down through the father, why did the writer of Hebrews refer to Jesus as the offspring or seed of Abraham?
He is referring to something else obviously since Christ had no human father. The statement of the seed of Abraham is in reference to the Abrahamic Covenant .
