Well, you are free to believe what you like, but this belief would be a denial of 1 Peter 4:1, Galatians 5:24, and Revelation 14:4-5.
I urge you to re-read these verses closely in prayer with God, my friend.
For if I am wrong, I have nothing to lose. But if you are wrong, you have everything to lose.
Please do not take that kind of chance, my friend.
Whatever is not of faith is sin (Romans 14:23).
You just said that everyone sins. So if sinning is the equivalent of not having faith according to Romans 14:23, and if you are agreeing with Hebrews 11:6 that says, "without faith it is impossible to please him." then you have to admit that you are not pleasing God. For sin is anything that is not of the faith (Romans 14:23).
But this has to be read in context of these verses, though.
1 "Since therefore Christ has suffered for us in the flesh, arm yourselves likewise with the same mind: for he that has suffered in the flesh has ceased from sin;
2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God.
3 For the time past of our life will suffice us to have done the will of the Gentiles, when we walked in licentiousness, lusts, excess of wine, reveling, carousing, and abominable idolatries:
4 In which they think it strange that you run not with them to the same excess of dissipation, speaking evil of you:"
(1 Peter 4:1-4).
In other words, verse 1 says they that have suffered in the flesh have CEASED from sin.
Verse 2 says these individuals (from verse 1) no longer live the rest of their time in the flesh to the lusts of men, but to the will of God.
Verse 3 says that these individuals use to live a sinful life as a part of their old life.
Verse 4 says that others in the world think it strange that these individuals no longer run in the type of sins they do, whereby as a result, they then speak evil of them.
First, you have to understand that Galatians is addressing the heresy of "circumcision" in going back to the Old Law.
Also, Paul is talking about one coming to the faith and not what one's faith should look like.
Anyways, Galatians is in context to the Law of Moses and not all whatsoever. For there is the Law of Christ (Galatians 6:2), the Law of Liberty (James 1:25) (James 2:12), the Royal Law (James 2:8), and the Law of the Spirit of Life in Christ Jesus (Romans 8:2) within the New Testament. Hebrews 7:12 says the Law has changed. So that does not mean God is against that which is lawful under the New Covenant. God is not unrighteous or lawless.
Anyways, we know Galatians 3 is talking about the Law of Moses in the Old Testament and not all law whatsoever because,
Paul says,
"And this I say, that the covenant, that was confirmed before by God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of no effect." (Galatians 3:17).
Paul also says,
24 "Therefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 But after faith is come, we are no longer under a schoolmaster."
(Galatians 3:24-25).
So we can see clearly here that Paul was talking about the Law of Moses and not all law whatsoever. For Paul never says that we can disobey Jesus and what he says. On the contrary,
Paul essentially says in Scripture,
"If any man speaks contrary to the words of Jesus Christ and the doctrine of Godliness, he is proud and he knows nothing"
(1 Timothy 6:3-4).
