To feel pity, or to not feel pity?

I feel the SS man does not deserve pity. At one point he says "The jews died quicklyand did not suffer as i do". Although they most likely did suffer, they knew that they would soon die, but just didnt know when. The jews had done nothing to anyone, but the SS soldier was guilty for killing many jews. He also states "Many young germans of my age die daily on the battlefields, they have fought against and fallen in the fight but i..i am left here with my guilt". He does not even mention that they are fighting defenseless people. He talks of all the germans dieing daily, but does not even care mention the helpless, harmless jews dieing daily.
