When someone dies in circumstances like this the people near to them are going to be very traumatised. Out of respect for them, you should keep your opinions to yourself. Using words like "unforgivable", "coward", and "duty" in the context of someone you appear not to have known is inappropriate and offensive.
That's your opinion. I don't think other people who are contemplating the same thing are helped by me (or anyone else) keeping things to myself.
Edit: changed my wording. I'm Dutch, we don't beat around the bush, but you have a point, I can say it differently. I will use those words for the people I did know. I do think that people should talk more; it is just strange how this happens if you actually HAVE people who care about you around you.
