Do you have any biblical reasons for your stated belief?
Because the bible states that all our righteousness is as filthy rags.
Isa 64:6 But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.
All our righteousness is not going to count as good enough.
We are carnal and selfish which is why we need to be born again
Mat 26:41 Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.
Mar 14:38 Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak.
God didn't give us a weak flesh at creation.
But we all have a weak flesh to overcome.
Rom 8:13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
Gal 5:16-17
16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. 17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
There are many verses that show that we are fallen and need to be born again.
We are not guilty of Adam's sin because sin is a choice.
1Jn 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Adam sinned and so do we but we are only guilty for the sins we choose to commit.
Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Because we sin = death
we all need Jesus
Rom 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
