The Great Commission, from Matthew 28: 18 Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you.
If you look at the teachings and works of the Christ, you'll find that his judgment was reserved for those in power, those who had the ability to do more for those around them, those who used their positions to accumulate more wealth and power and influence rather than lift up those who had little. The beatitudes shared at the Sermon on the Mount were a direct attack at those in power - the Sanhedrin, Herod, Rome, etc.
You also use a definition of sin that doesn't fit hermeneutically. "Sin" means "to miss the mark", as in archery - more literally, to fail to achieve the desired result. Disobedience is not sin; it hits the desired target dead center. It is its own thing.
If I'm following the examples and teachings of Jesus, then I'm healing the child of the occupying enemy force. I'm saving the adultress from the hands of a bloodthirsty mob wanting justice. I'm multiplying food and giving it without question to a hungry crowd. I'm calling government and religious leaders out on their self-promoting and self-benefiting practices.
And Christ said "So have you done to the least of these, you have done also to me."
