I think the question is about is persons righteous or not. If person is righteous, he produces righteous "fruit". And if person is unrighteous (sinful), he produces sinful actions. Even if you would be lazy and not produce much evil it doesn't really matter, if your mind is evil. Small evil is enough to prove what kind of person one is. The actions are only like a fruit that tells is the tree good or bad. Actions don't define person; it is the person that defines his actions. Actions are only the result, not the cause.
Even so, every good tree produces good fruit; but the corrupt tree produces evil fruit. A good tree can’t produce evil fruit, neither can a corrupt tree produce good fruit. Every tree that doesn’t grow good fruit is cut down, and thrown into the fire. Therefore, by their fruits you will know them.
Matt. 7:17-20
He who does righteousness is righteous, even as he is righteous. He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, that he might destroy the works of the devil. Whoever is born of God doesn't commit sin, because his seed remains in him; and he can't sin, because he is born of God. In this the children of God are revealed, and the children of the devil. Whoever doesn't do righteousness is not of God, neither is he who doesn't love his brother.
1 John 3:7-10
This is why I think sin is what sinner does. And righteousness is what righteous does. All sinners are as bad, even if they would not have done all the same things. And all righteous are as good, even if they would not have done all the same things. What matters is that their state of mind, because it is the cause of all their actions.
