"1.3 I believe this diagnosis can be considered as a significant contributing factor. 1.4 [The appellant] has developed, during his early years, certain strategies to help him cope with adversity; he kept others at a distance and entertained little sympathy for the plight of others. He focused on duty and expected the same from others. These strategies served him well in the army, but were, nevertheless, not sufficient to protect him from trauma. 1.5 Although these strategies became increasingly maladaptive when he returned to civilian life, they still enabled him to carry on functioning. Keeping the trauma out of his mind put them under considerable strain; to avoid any further demands placed on him by others, he became even more detached and intransigent. This came at a cost as it left him painfully lonely and distressed. 1.6 Abusing his daughters and niece seems to have been a grossly inappropriate attempt to find some kind of solace, intimacy and connection, and to alleviate his distress while remaining in complete control of the situation."
"The sentencer should make an initial assessment of culpability in accordance with any relevant offence-specific guideline, and should then consider whether culpability was reduced by reason of the impairment or disorder. Culpability will only be reduced if there is sufficient connection between the offender's impairment or disorder and the offending behaviour. In some cases, the impairment or disorder may mean that culpability is significantly reduced. In other cases, the impairment or disorder may have no relevance to culpability. A careful analysis of all the circumstances of the case and all relevant materials is therefore required."
