No. I agree that people deserve a second chance, but there is no reason for him to be in the money business. He should be doing one of the other 95% of jobs that do not require it.
There is no reason to trust him with any money and the authors conclusion that it was worth it because he found a deduction is absurd. Any tax account should find you the same thing and she deserves anything she gets from having this guy know her (and her mother's) financial details.
