On Arrakis: Most of the accomplishments in BM require you to spend a lot of time. If you're part of a likeminded group that's fine since you can delegate. If you're alone, against a behemoth like SA, it's a different story. He was ambitious and kept piling the hay on his fork, more than that, he's enthusiastic enough about BM to have been dragged into it multiple times. Sure, most (all) of us prefer to see the story through till the end but that doesn't mean someone should just keep on playing for our entertainment. If he's tired of it, let him quit. During the time he played at least he did stuff, changed things and inspired a ton of conflict.
