Yeah I think that that wasn't happening anyway,
I mean it's basically the same as a man disposing of the body without dismembering it.
And once you're done butchering your dead husband body I'd think you're not right in the head anymore so yeah...
And again most women killers that dispose of the bodies put them in pieces, I don't think it's because they're anything different more than they can't move the bloody thing in the first place.
It's a grim prospect anyway I'd say.
If she dismembered them alive then YES that is significantly sicker than most killers.
