26 It need, however, hardly be emphasised that the respondent's long history of criminal conduct, much of which consisted of committing similar types of offences as the present, combined with the fact that he was on parole at the time of committing these offences, increased the need for deterrence, both specific and general, and for the protection of the community. An offender's antecedents provides an indication of moral culpability, prospects of rehabilitation, the existence of any dangerous propensity, the need for community protection and the increased need for specific deterrence having regard to the failure of previous penalties to moderate his behaviour.[9] Regard must also be had to Parliament's intention, evidenced by the very high statutory maximum fixed, that the crime of aggravated burglary should be viewed as a very serious offence. It is incumbent upon this Court to ensure the maintenance of appropriate sentencing standards in this State for crimes such as these which destroy people's domestic security and erode their capacity to feel safe in their own homes. The effect on the victims, who here included the very elderly, should not be underestimated. The frequency and nature of the respondent's violation of the privacy and sanctity of each victim's home and the theft of property constituted serious examples of these crimes.[10]
