Yup, CW is cold and callous. IMO, death rituals are primeval.
Animals perform them - elephants mourn and bury their dead by covering with leaves. Its been documented that ravens will stay with a dead partner and mourn them too.
When our beloved pets have died, DH and I have buried them next to their friends who have passed before -- because in some instinctive/primitive way, I'm hoping they will be companions in the after-life, even though I am not religious and consider myself agnostic. In my grief I was afraid that my recently deceased pet would be cold, hungry, scared, lost -- even though rationally I knew they were dead and could not feel those things.
Death and burial is solemn and important, for humans and certain animal species.
The fact CW disposed of his children's bodies in such a hideous, thoughtless way makes me ill. He discarded their lifeless little bodies as though they were garbage and his only thought was to cover his OWN rotten hide.
