His evidence continued that the family history of the appellant, including the early disruption to the family, institutional care, and a whole series of group homes were properly described as aggravating factors, and that his history of family and relationships included "an impressive sort of cumulative effect in his case". Dr Walton also said that depressive or deficient personal circumstances affected personality disorders in that "particularly persons suffering from this type of personality disorder are not well-equipped to cope with demands to adapt and the normal vicissitudes of life are often beyond them in terms of coping skills". He added that "the more difficult external circumstances are, the more likely maladaptive behaviour is to occur". Dr Walton said that in the circumstances in which the appellant found himself before the offences occurred, where his relationship with Ms Reeve had deteriorated to the point that his belongings had been piled up in the backyard and burnt by the deceased, and he had returned to find that he had been dispossessed of his property and had nowhere to stay, that he thought the appellant was likely to find that situation particularly challenging.
