I do think you ought to remove the phrase, "...but despite having paid everyone back..." That phrasing comes off to me as a bit of a justification for what you did and seems to indicate a feeling that you should not have been sentenced. I don't know if this is your intent or if indeed such a belief is justified. It may be off putting to some.
Edit: removed that bit as well as "I went on to build a large financial services firm". Thanks for pointing this out.
