Then you must be familiar with Paul sending runaway slave Onesimus back to his master Philemon. I've read some Aquinas, Calvin and Luther and don't recall any 'Absolving of Original Sin' for doing good deeds but maybe I missed it.
The Civil War/World War II Connection
Former U.S. President John Tyler Became Loyal to the Confederacy
Slavery was Americas original sin. That I know of General George S. Patton didn’t own slaves. The Confederacy was an evil institution that engaged in violent rebellion to secede from the Union and started a war to preserve it. “Slave’’ was more often a term in the Biblical term of a person who worked for another. As is typical of you you use verbal gymnastics and convoluted logic to fit your view of history. And in case you haven’t noticed bird brain, the Confederacy is long gone. They lost remember?
