There's nothing disrespectful about discussing an accident if, as Wally says, it's done respectfully.
When one happens, the natural reaction of any pilot is to ask "What went wrong, and why?" This leads to conjecture about possible causes, similar events, near-miss type experiences we've all probably had.
No-one can assign blame, and that's not the aim - it's to put together a mental picture of what might have gone on; a reminder to ourselves and others of what can happen, and what steps we ourselves can take to make sure we fly as safely as possible.
A sad event like this is terrible for the family and friends, of course, but I don't think it's presuming too much to suggest they'd want others to learn from it.
