Therefore, if a defendant's purpose in acting is not to produce the actus reus of the crime with which he has been charged and intention is the only type of mens rea available, he may still be found to have an intention to commit that actus reus if he has oblique intent. This is where the consequence is not the defendant's purpose but rather a side effect that he accepts as an inevitable or certain accompaniment to his direct intention. The consequence here does not have to be 'desired'. Indeed, the defendant may even regret that this incidental consequence will occur. The need to refer to oblique intent is rare and should only be used if the facts require it.
