The Bugmy principles regarding childhood deprivation and moral culpability do not require a threshold of 'profound' or 'significant' deprivation before they can be engaged. Any childhood deprivation may potentially reduce moral culpability, and the general (first) way identified in Bugmy does not require a causal nexus between the deprivation and the offending. However, the specific (second) way does require such a causal link, and it remains open to a sentencing judge to find that no such link exists where the offending is driven by a diagnosed disorder rather than the childhood deprivation.
