2 infants die in parents bed...co-sleeping

Just heard about this story last night.
These parents did it twice. I can't even fathom how someone could do this (co-sleeping) a second time after losing their first child this way. 1st time could be a mistake, but to do it again is just ...... I don't know the word to use. Evil?
