The intent is limited to the act itself and the person has no other criminal purpose in mind. Actual intent to perform some act, but without a wish for the consequences that result from that act.
(ex: in the case of assault, the crown only has to prove that action was being committed, not if there was any alterior motives. X assaulted Y, we don’t need to know if it was to kill Y or to rob from Y-only needs to prove actus reus)
