Book Reports / 'the Nazi in The Sunflower is asking for forgiveness' - Thesis Statement! [2]

I'm trying to find the perfect thesis statement for a paper I am writing. The paper is on the Holocaust and whether or not a Jew could forgive a dying Nazi when asked. (It's over the book The Sunflower) I'm trying to prove that there is no way to decipher if he should or shouldn't have because there are really strong factors supporting both forgiving and not forgiving him. So far I don't have much...

Thesis Statement:

With extenuating factors supporting the Nazi in The Sunflower is asking for forgiveness both out of guilt and atonement, there is no possible way to decipher if he should or should not be forgiven.

I'm arguing my point using factors such as:
he is on his deathbed asking for forgiveness- he's Catholic and just wants forgiveness to set himself free, or he has had time to think about his wrong doings.

he had to join Hitlers army because he had to protect himself and his family- but everyone knows what was happening and it wasn't okay.

and etc.

Any help?! It would be greatly appreciated.
