Its motivation pretty postive
Black men are being victimized because of the accusation that they raped white women, but of this there is no history, it was a motive that was used to justify the lynching. That blacks were inferior to whites and therefore there was justification for this society as a whole to be overthrown. Also because they were becoming a primitive race.
Arthur should not forgive Lancelot due to his disloyalty because it greatly affected him and his life. His wife, Guinevere, was having an affair with Lancelot and it took a toll on him. Arthur should only forgive Lancelot if Lancelot earned his trust back once again.
Sir Gawain is loyal to King Arthur because he proved that he can be loyal and chivalrous when no one stood up against the Green Knight. He stood up against the Green Knight despite the fact that he was still not a knight.
Yes, loyalty can be restored even if it was once lost. It can be restored as long as the person was willing to trust the person who betrayed him once again and if the person who betrayed him earned back his trust.
