Having witnessed the travesty that was my uncle's burial (of ashes) and the wrangling over who got to do what with them, and who did underhanded things in order to get their way secretly, I'm not surprised. Families do whatever they want with the dead. The amount of respect actually shown to someone who's dead can be abysmal. If they're not fighting over your money they're probably fighting over who gets to arrange the funeral details.
I would often say "I'd like to die on Everest" to certain family members and when they'd ask why, I'd say "so you lot don't get your hands on my corpse". The thought of what utter (unheartfelt) crap they'd be saying at a funeral makes me cringe, too. Oh well, on the plus side, I'll be very unconcerned at the time.
