There was no attempt in it to justify anything.
The was no agenda.

And the writing was very personal.
You could feel every circumstance he was describing.

Not having read, "I, Willie Sutton", I can't know what contradictions anyone could be talking about. But since, as I said, in the book I read, he is not trying to glorify himself, or to blame anyone but himself for anything, I can't imagine what contradictions of any substance would be even possible.

The part where he mentions the routine purchasing of paroles did not seem accusatory to me. It was just mentioned, almost in passing.

I agree with you about the descriptions of his escapes.
They are thrilling and nerve-wracking. I felt as if I were there.

The Times review to which you link was the one concerning the novelized biography - not the one written by Willie Sutton himself. I prefer autobiographies. You can really tell, imo, when someone is being straightforward. There is a certain flow to the writing.

I was particularly moved, if that is the word, by his statement that it wasn't about money - although that was obviously part of it - he just loved robbing banks and felt most alive when doing so. (my paraphrasing)

I think that kind of declaration puts him into the realm of the artist. I can say that about him because, according to what I believe to be true, he never hurt anyone - except, I guess, himself.
