I work in health care and specifically around the dying. I'll just share what I've seen over 20 years. Seen many cultures, many family dynamics at time of death. This is anecdotal of course. These are just examples I've encountered many times. Highly religious people counter intuitively had the toughest time accepting and dealing with death and dying. Prominently it was Catholics (or more broadly Christians). The ones with bibles in their hands at all times, praying before and after everything, were actually the most fearful of death. Which has always been really weird to me, because I'd always assumed their faith gave them confidence they were going to a better place in a new life. But surprisingly time and time again, the idea of letting go was terrifying and excruciating for them. Rather than seeing them embrace it, there was palpable dread. I saw this whether it was north American Caucasians, Filipinos, or Africans.
The most accepting were often atheist European. Germans seemed especially pragmatic. Chinese, whether atheist or Buddhist, the most aggressively medical seeking, as a duty to their elders to try every heroic medical effort available. Indian, medically focused yet pragmatic. Usually graceful in their acceptance of circumstances. Jewish, pragmatic. Japanese pragmatic.
Filipino by far the most superstitious, followed by African. By this I mean they believed in miracles very strongly, the idea prayer and mind over matter, denial was prominent. They'd believe till the end someone can and will get better. I’ve never heard such wailing as with Italian, Portuguese, and Filipino families. It seems like it’s there cultural duty to cry as loudly as possible when the time comes. North American Indigenous were the most graceful in accepting death and dying by far. Equally stoic and at peace with what comes next yet heavily bereaved and mournful of the loss.
Again this is limited to my personal experience, and how these individuals dealt with death does not necessarily reflect on their people or their culture as a whole. I'm just noting a stereotype that I've seen over 2 decades. No offence intended.
