And now the Crown wants her declared a dangerous offender and locked up behind bars indefinitely.
On Monday, a judge heard closing arguments in Papin's dangerous offender hearing, which stems from an aggravated assault conviction for an Aug. 4, 2010 stabbing.
Crown prosecutors Tania Holland and James Rowan argued Papin, 46, has a lengthy criminal history with a pattern of assaultive behaviour that psychological experts conclude demonstrates she poses a risk to the public due to the high likelihood she will re-offend.
"She's getting worse," said Holland, who said Papin has been diagnosed with antisocial personality disorder and labelled a psychopath.
"She just can't stop," Holland said.
Papin was convicted of aggravated assault on Feb. 10, 2011, for the 2010 stabbing of Simon Martin.
Court heard at trial that Papin and Martin were living together and she stabbed him three times in the chest with a kitchen knife during an apparent argument.
Police found Martin on the floor in the hallway near his apartment with a trail of blood leading back to the suite.
Papin emerged from the suite covered in blood.
After being arrested and put in a cell, Papin was seen trying to clean the blood off of herself by licking her arms and hands.
Since 1991, Papin has been convicted of three counts of aggravated assault, five counts of assault with a weapon, six counts of assaulting a peace officer, robbery and three counts of possessing a dangerous of prohibited weapon.
She was acquitted of second-degree murder in 1990 as a result of battered woman syndrome.
Defence lawyer Alex Millman disputed that Papin has demonstrated a pattern of violent offences to the extent the Crown is suggesting and noted most of her violent offences have occurred while she was behind bars.
Millman argued Papin should not be designated a dangerous offender and said she should get two to three years for the aggravated assault and then be strictly supervised in the community as a long-term offender.
Papin tearfully told the judge that she knows she has made a lot of mistakes and hurt a lot of people and said she is sorry for what happened to Martin.
A decision is slated for either early March or mid-April.
