The once-beloved comedian could be sentenced to up to 30 years behind bars, though O'Neill has wide latitude in determining a sentence for the 81-year-old Cosby - the first celebrity to be sentenced during the #MeToo movement.
"He seemingly thinks that he hasn't done anything wrong".
Montgomery County District Attorney Kevin Steele rejected the notion that "age, infirmity, should somehow equate to mercy".
"This is about a person who put himself in a situation of being a mentor, but we know he had other intentions just from the beginning", he added.
Cosby refused to cooperate, which he was rightfully allowed to do, so Dudley said she relied on transcripts from both of his criminal trials.
"No one is above the law, and no one should be treated differently or disproportionally", O'Neill said.
Prosecutors asked for five to 10 years in prison.
"Now, nearly 15 years later, I'm a middle-aged woman who's been stuck in a holding pattern for most of her adult life, unable to heal fully or to move forward". However, judges are allowed to issue sentences beyond those guidelines.
"I have testified, I have given you my victim impact statement", Constand said. "Mr. Cosby, this has all circled back to you".
The morning session of the sentencing hearing was devoted to whether Cosby would have to register as a SVP (sexually violent predator).

There was no immediate comment from Saudi Arabia on Mr Rouhani's allegations. The U.A.E is a Saudi ally, and hosts a significant USA military presence.
"The behaviors are beyond their controls", she explained in court, "so they are urged to act on it".
"He is likely to re-offend", said Kristen Dudley, a psychologist and member of the Pennsylvania Sexual Offenders Assessment Board that conducted an evaluation on Cosby this summer.
Cosby's lawyers argued, too, that the state law on classifying sexual predators is unconstitutional.
Among other things, Wyatt said all three of the psychologists who testified against Cosby were "white women who make money off of accusing black men of being sexual predators", and he accused prosecutors of using a doctored recording of a telephone conversation between Constand's mother and Cosby.
Chelan Lasha, another of Cosby's alleged victims, also praised the sentence.
Cosby arrived Monday and Tuesday with his spokespeople, Wyatt and Ebonee Benson.
Cosby, the groundbreaking actor and comedian, did not testify at the trial.
Green downplayed the outburst on Monday when requesting that Cosby receive house arrest.
Hopefully, Cosby gets appropriate punishment this time.
His lawyers have said he will appeal the conviction, which observers say could push the case up to Pennsylvania's highest court and take several years.
Cosby faces the possibility of years in prison.
The judge will also have to decide whether Cosby is permitted to remain free pending his probable appeal - but this is thought to be an unlikely result, with sexual assault campaigners keen to see him finally jailed for his crimes.
