I'm going to post an alternate view of NN that may not be popular, and isn't necessarily entirely my view, but I'm just throwing it out as devil's advocate...
Imagine your husband has left you for someone else who was part of a friendship/poly group with you. You're still angry and trying to get over this when all of a sudden they both go missing and it's announced on FB that they're married and having a baby. It starts to become big news, international news even because everyone thinks you're the one updating his FB and that they're missing. You're not the one updating, so you're pretty convinced it's CDC himself and he's being pretty horrible... Not the man you thought you married at all! In fact, you don't care that they've gone, you just want them out of your life!
Then you find out the truth. You still loved him. You didn't mean the above...
The is not the brightest decision. We know that... But in her world, she might genuinely not have the means to pay for his funeral and is still listed as next of kin. What's the situation there, do we actually know if she's responsible for funeral arrangements? Someone might have suggested the to her and she's not thought of the backlash it could create...
Maybe she is money grabbing and callous... But I think we should also consider the option that she's actually grieving both the loss of her marriage and the murder of CDC and we should hang fire on making too many strong judgments against her at this stage. I feel like everyone's quick to hate on her when, in reality, she's also going through a pretty awful situation, whether we like how she's been dealing with it, or not.
Maybe I'm wrong, maybe I'll eat my words, but I think we should possibly focus our grievances elsewhere right now until we know.
