To me, moral integrity is to make selfless decisions or actions whenever facing a moral dilemma. An action that is made because of pure belief or just following the your conscience, whether if it is right or wrong regardless of the consequences that will most likely to follow.
Maximillian Kolbe is regarded as a Christian of great moral integrity. Whilst in prison at Auschwitz, he was often beaten by soldiers if he ever became tired and just stopped working. He was a priest and despite being torchered and being constantly beaten up soilders, he still managed to comfort the other prisoners and taught them the way of God. Kolbe continued his duties as a priest and heard confessions from the other prisoners. He even volunteered to move the corpses of the prisoners who had been torchered and died. He had many times smuggled bread and wine and celebrate mass, obviously secretly so the soildiers won’t see. During the time he spent in prison some people had escaped from prison. As a consequence, people had to be killed to make up for the punishment. Ten men were chosen to die, one of which had a family. Kolbe begged the soldiers to swap places with this man. He convinced them by telling the soldiers that he was a catholic priest, old and useless.
I think Kolbe decided to sacrifice himself for the man because he believed that it was the right thing to do, he might have even followed in the footsteps of Jesus, as Jesus sacrificed himself for the world. As Kolbe saw himself as an aged priest and had no family, and the young man had his own family to raise. The young man may perhaps one day return back to his family.
