It would make sense. Even if they aren't our direct ancestors, they're still spirits that deserve to be honored in their own right. I personally can't help but wonder what happened during their lifetimes, because there are ways to become corrupted enough that you can never join your ancestors, even in death, where I come from.

Such things are always sad to see.
