I'm always reminded of the jailed killer who hasn't denied his acts and behavior suddenly finding God and doing the Lord's work. "I've been rehabilitated and deserve another chance in society" the lament goes, I'm worthy of citizenry again and worthy of trust within the national community.
In Cohen's statement to the judge, "I take responsibility for my actions … this moment is my freedom from the incarceration of the tyranny by the man I respected in business... I will lead my life as it was intended and be more thoughtful in my endeavors...". Basically, I'm a changed man and deserve my freedom.
