(1) An offence shall not be regarded as more serious for the purposes of any provision of this Code by reason of any previous convictions of the offender or any failure on the part of the offender to respond to previous sentences.
(2) Where any aggravating factors of an offence are disclosed by the circumstances of other offences committed by the offender, nothing in this Code prevents the Court from taking those factors into account for the purpose of forming an opinion as to the seriousness of the offence.
