Is this some AI offering? Either way an alarming number of people would use it. Imagine you've lost a child or a spouse or a pet, or a parent? How different is it from watching videos of them? Probably would cause more long term psychological damage, I'll grant you.
I think that answers itself with minimal thought.
Struth, we're already rubbish enough in Western society at dealing with death, let's not pretend even more than the "passed away", "passed", "slipped away", "Went to sleep" euphemisms. FFS. "Dead" and "died" are the words.
The human emotion of grief has evolved with the human brain to help make sense of losing people you can't imagine not having around, and to deny that emotion would be as destructive as denying happiness or any other emotion: it's part of what makes us human, however hard it is to deal with.
If you can bear a Shakespeare sonnet...
When to the sessions of sweet silent thought
I summon up remembrance of things past,
I sigh the lack of many a thing I sought,
And with old woes new wail my dear time's waste:
Then can I drown an eye, unus'd to flow,
For precious friends hid in death's dateless night,
And weep afresh love's long since cancell'd woe,
And moan th' expense of many a vanish'd sight;
Then can I grieve at grievances foregone,
And heavily from woe to woe tell o'er
The sad account of fore-bemoaned moan,
Which I new pay as if not paid before.
But if the while I think on thee, dear friend,
All losses are restor'd, and sorrows end.
