Possibly, I'd give it the benefit of the doubt. Either way, I think it is fair to note that other cultures see death & remembrance in different ways.

Curious how you find other cultures and belief systems are? In Hinduism, at least I can attest that there is the concept of "mourn and move on" in that the body is not even preserved, it is freed of its physical form through cremation. The fire into the funeral pyre is instilled by hand by the eldest son - it's a poetic closure.

If you do a search for "ancestor worship" you'll find a few examples. It seems more common among Asian cultures, perhaps specifically those with a Buddhist tradition, but that's what I happen to be more familiar with so it may be common outside of that as well.
