No, there is plenty of human good. The difference is that human good, separate from God, is parlayed into evil as a policy of Satan, to produce a counterfeit Millenium and perfect worldly environment, i.e. a worldly system, the KOSMOS.
This is an important tool to use when we fall into soulish perspectives, though some believers might be more prone to lasciviousness, than legalism.
Here is an example. A person who was raised in a Judeo-Christian CULTURE, and believes God exists by rationalistic argument, but never through faith in the person of the Son of God, our Lord and Savior Christ Jesus, yearns to perform 'good works' in order to further his position with God on his own works, rather than through faith in Christ. Perhaps he observes or hears about how freemasons build hospitals for burn victims and orphans, rendering medical treatment free of financial burden to those who are poor and suffering physically.
Such a person might indeed perform good works in building such hospitals, but when they are built and operated WITHOUT faith through Christ, they instead are parlayed into evil as a counterfeit plan by Satan to create a perfect world environment independent of God's plan.
The good still exists, but it is a human good void of divine righteousness, that still will result in a final judgment of something that is good for nothingness.
All good originates with the Divine. In the charitable act you describe as an example, I will assume that the fellow loves God as he understands him and is charitable to the neighbor. If he is doing these acts for no benefit to himself - WHAT DIFFERENCE is what he knows the Lord's name as?
If you love God, love the neighbor and live a good live you will go to heaven. If you love yourself, love the world and live a life of evil you will go to hell.
