'aberration' or 'deviation', may be: deviation from morality (sīla-vipatti), or deviation from understanding (ditthivipatti).
"To deviate in deeds, or in words, or in both deeds and words: this is called deviation from morality.
" 'Alms and offerings are useless, there is no fruit and result of good and bad actions, there are no such things as this and the next life' .... Such wrong views are called deviation from understanding." (Pug. 67, 68)
