It's up to you to decide. Those obligations are usually for the living to feel good. The dead probably don't care that much.
When it comes to inheritance I think this should be respected. If a dead person wants to leave his watch collection to a friend, the family shouldn't interfere.
Don't feed the Russian trolls. There are quite a few here, better not engage with them.
The problem is they are scaring people of from here with their arrogant tone and misinformations.
I wonder how much they are getting paid, or if they are only useful idiots.
