I don't believe humans are "meant" to do anything. We are a result of evolution, not intentional design. So I believe humans should do whatever they personally want to do in a situation like this.
If you have a loved one who does this and you don't feel comfortable interacting with their AI version, then don't interact with their AI version. That's on you. But don't belittle them for having preferences different from your own. Different people want different things and deal with death in different ways.
