Brother, what you have typed here is utter nonsense-you say Jesus was prone to sinful propensities/law of sin/death-- "working in His members?"
Rom 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Rom 8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
Rom 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
The law of the Spirit of life (ho nomos tou pneumatos tēs zōēs). The principle or authority exercised by the Holy Spirit which bestows life and which rests “in Christ Jesus.”
Made me free (ēleutherōsen me). First aorist active indicative of the old verb eleutheroō for which see note on Gal_5:1. Aleph B have se (thee) instead of me. It matters little. We are pardoned, we are free from the old law of sin and death (7:7-24), we are able by the help of the Holy Spirit to live the new life in Christ.
In the likeness of sinful flesh
Lit., of the flesh of sin. The choice of words is especially noteworthy. Paul does not say simply, “He came in flesh” (1Jn_4:2; 1Ti_3:16), for this would not have expressed the bond between Christ's manhood and sin. Not in the flesh of sin, which would have represented Him as partaking of sin. Not in the likeness of flesh, since He was really and entirely human; but, in the likeness of the flesh of sin: really human, conformed in appearance to the flesh whose characteristic is sin, yet sinless. “Christ appeared in a body which was like that of other men in so far as it consisted of flesh, and was unlike in so far as the flesh was not flesh of sin” (Dickson).
For sin (περὶ ἁμαρτίας)
The preposition expresses the whole relation of the mission of Christ to sin. The special relation is stated in condemned. For sin - to atone, to destroy, to save and sanctify its victims.
Condemned
Deposed from its dominion, a thing impossible to the law, which could pronounce judgment and inflict penalty, but not dethrone. Christ's holy character was a condemnation of unholiness. Construe in the flesh with condemned.

If, as you suggest, the "law of sin and death working in His own members" then why the need to "atone for the sins of the whole world?"
Who is Yeshua to you? Man, Son of man, ο υιος του θεου-God? Just answer me this question.
Bereshis (in the Beginning) was the Dvar Hashem [YESHAYAH 55:11; BERESHIS 1:1], and the Dvar Hashem was agav (along with) Hashem [MISHLE 8:30; 30:4], and the Dvar Hashem was nothing less, by nature, than Elohim! [Psa 56:11(10); Yn 17:5; Rev. 19:13]
You see that? Messiah is, by nature, God!
