In this particular case, we should have options, but those options are there to impress upon us that nothing we do or say will dissuade this creature from his duty; it should reinforce his nature.
This entity has a duty, and nothing we mortals say or do has any impact upon that; what we, simple mortals, want doesn't come into it - he will do his duty, whether we want him to or not.
I feel like Larian are completely jumping the shark to actually make this entity Jergal himself- that's *stupid* and it also doesn't really fit with the way deities work in the realms (So... that's probably exactly what they're doing... /cynical). They do not and cannot manifest physically in the realms themselves, except in particularly dramatic situations that are world-shaking events. What he should be is a chosen envoy of the Scribe, given a duty to fulfil by the Scribe, and the divinely-given powers necessary to carry out that duty, which should put him well enough beyond our abilities to interfere with.
