Greg, sinners may be buried, and in consecrated ground if desired. But to erect eulogistic tablets on their graves listing their wonderful works when in fact they were intrinsically evil goes beyond the pale.
Regarding his relatives, one can surely feel for them. They must be horrified and disgusted in equal measure. And I expect ignorant folk will try to get at them simply because they ARE his kin. If I found out a member of my family was a rapist and a paedophile I would suffer from shock and (illogically) shame.
