What's a good death and how it's measured is obviously super subjective. But I like to think a satisfying death is a good death. Like when you read a story and a character you like dies, but it was such a damn good death that you can't even be mad.
For instance, my ideal death is very satisfying to me. I go on a backpacking trip and jump off a cliff an fall a great height and/or into frigid water. It ties into past memories (of backpacking), it's my ideal method (jumping), and if I could delete all presence of sasu involvement beforehand and manage to distance from friends, I think it would be even more of a "good death". It feels solid, thought out, full, and wonderful. Though it'll likely never end like that.
