First, Torn takes deaths very seriously. They are confirmed through obituaries, if I remember correctly.
As for a Will in Torn, sure, it'd be an endearing change. I imagine though that the people who really really care about that kind of thing and are worried about their passing enough to have a will of some form already do something to ensure their stuff goes somewhere. I've personally considered putting it in my own will irl (if I'm still playing into older age), my family already knows how important this game is to me so in the event that something happens unexpectedly, they know I'd want my stuff to be given away, and some people have the opportunity to give their stuff away before their passing, like roadhousee did o7.
