Hello Levi, I'm not sure who you are agreeing with about that (as I literally know of no one who does, nor of any church, not even at the farthest reaches of the pale of Christian orthodoxy). That said, why do 'you' believe this about Him? What led you to this conclusion, IOW? Thanks
Also, while we are on the topic (and just for clarity's sake), since the Lord Jesus is "the very image of the invisible God" .. e.g. 2 Corinthians 4:4; Colossians 1:15, do you also believe that God the Father has a sinful nature too (if not, why not?)
There are several reasons why neither the Bible, nor the entirety of historic Christianity has ever agreed with you about that either. Even the demons knew both who He was and what He was. For instance,
Luke 4
33 In the synagogue there was a man possessed by the spirit of an unclean demon, and he cried out with a loud voice,
34 “Let us alone! What business do we have with each other, Jesus of Nazareth? Have You come to destroy us? I know who You are—the ~Holy~ One of God!”
Here are just a few more for good measure
2 Corinthians 5
21 He made ~Him who knew no sin~ to be sin on our behalf, so that we might become the righteousness of God in Him.
Hebrews 4
15 We do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet ~without sin~.
Hebrews 7
26 It was fitting for us to have such a high priest, holy, innocent, undefiled, ~separated from sinners~ and exalted above the heavens.
1 Peter 2
21 You have been called for this purpose, since Christ also suffered for you, leaving you an example for you to follow in His steps,
22 WHO ~COMMITTED NO SIN~, NOR WAS ANY DECEIT FOUND IN HIS MOUTH;
23 and while being reviled, He did not revile in return; while suffering, He uttered no threats, but kept entrusting Himself to Him who judges righteously.
1 John 3
5 You know that He appeared in order to take away sins; and in Him there is no sin.
If the Lord Jesus is not the Spotless Lamb of God that the Bible tells us that He is, but is instead, a sinner (like we are), then His death on the Cross would not have been capable of saving Him or us!!
God bless you!!

1 Peter 1
18 You were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers,
19 but with precious blood, as of a lamb ~unblemished and spotless~, the blood of Christ.
