I think you misunderstand me. I don't know and I don't care about Thunts decision making process.

Look, it's possible for both of the below to be true:
I want Ears to lose his ears in some gruesome display of determination
I want Ears to die in heroically spectacular fashion

Right? He can have set out - 20 years ago - with both goals in mind. And at some point, he felt the plot called for Ears to die, despite him still having his ears - but then he got another inspiration, and now we have the opposite situation: Ears loses his ears, but did not (yet!) die in a display of spectacular heroics and self-sacrifice.

But all of that ... doesn't matter. Ears factually did not die, no matter what Thunt's plans and thoughts were right up until the very moment he published the page. Thunt, in principle, is secondary. The narrative is primary. Ears was not meant to die, because if he was - then he would be dead.
