Sundering stuff established in the Q&A

Perhaps now you will appreciate why Kizuya wanted to see that scene play out.

I actually expect that Kizuya wants to see the scene play out for much the reason that I, a couple posts above yours, outlined why Elidibus can never provide an unbiased source: because even if he was at one point an unbiased source on a personal level (which I'm not convinced of, but will concede that it's plausible, even if it's not important), narratively he is not, because we know where he ends up going. Elidibus' perspective therefore cannot be read as in any way neutral, because we know the context isn't a completely neutral account of facts: it's 'how Elidibus ultimately decided to go for Plan Zodiark'.

I think the reason Kizuna decided that the 'unbiased account' they wanted was specifically from Elidibus was because of exactly that. Their view on this is pretty blatantly worn in their signature, they think Hydaelyn's outlook is terrible and cruel. They chose Elidibus as their 'unbiased' person because he would give exactly the statement they want to hear: 'from my neutral perspective, Zodiark Is Right'.
