The reason why i like the eternal struggle is because it leaves room for another story in the situation where he escapes and begins his evil plans again.

It's a continuation of a story and unlocking the potential story to what could have been.

Yes he was a bad guy, but i liked his brand of bad guy to the degree that i would have loved to see how his story would have ended in getting his way, then maybe there could be some time travel involved and fix the timeline.

The idea behind the Baal future was kind of meh, because it skipped over the good stuff and the audience never saw how that worked out, i don't like the anticlimactic ending, because it's boring and doesn't share the gravity of the story in a meaningful enough way.

But if he were to die i would hope it was done via a lore friendly way in such the ways of the OTHERS in how they handled Danial, with Danial they pretty much erased all knowledge from his physical form, however Oma left some knowledge so that he could retain who he was before and after his ascension.

However i could see a way the others could strip everything from Anubis and separate him from the soul of whom he was inside of, because the way Oma was tricked by Anubis allowed her to ascend both entities at the same time but not knowing about the Goa'uld ascending, now i have my own theories in how such a thing was possible and i suspect the OTHERS had something to do with Anubis coming across the information to catch her in the act, meaning they gave him the tools and methods to trick his way into being ascended.

But outside that theory they could strip Anubis from the host and release them both back to their lives before they ever blended and all the knowledge of who they were, without leaving any trace of who they were.

Anubis would once again be a symbiote and his host would just be a human on some random planet and none of them would have any prior knowledge of who they were, it's not exactly death but it's a solution i could see coming from the ascended beings in the milky way as a ultimatum method in handling the Anubis situation.

I liked Anubis a lot as a antagonist but I wished his reasons were fleshed out more. He didn't totally seem like a "more evil Goa'uld" that hungered for power over the Empire itself but also maybe even Godhood if that was his ambition as he became "half-ascended" form. He also somehow reminds me of Sutekh from Doctor Who besides resembling a jackal in myth and such.
