Yes there's other issues at play in the judgement, 11 children, all known to social services, abusive relationships, police intervention.
Completely irrelevant - in fact, it makes what he did even worse because it implies...no, confirms..his actions were a moral judgement! How many children must a woman have in precarious circumstances before drs are allowed to sterilise without consent?
It's really appalling that any details of this woman's life were made public; the only facts important were he sterilised her against her wishes. It's reminiscent of courts allowing discussions of how many sexual partners a woman has had in rape cases; it shifts the pendulum of blame towards the woman for a man's actions and leads to discussions around 'mitigating circumstances' on a feminism board 
Zero excuse for this, he should be in a prison cell!
