How do you account for the frequent admissions of the biblical authors' failings and weaknesses within their own writings; also Paul's statement that he persecuted Christians? You said earlier that that must have been how they wanted to portray themselves in the story. If you are correct, why did they not renounce their story when tortured?
The only other explanation I can think of is that they were insane. But I would expect an insane person to fight to prevent arrest.
As the earthworm said, "the problem is, there is no problem"!

You are supporting anecdotal reports made by those with a vested interest that claim a miracle: given the culture of the time people were more credulous regarding religious superstitions and miracle claims. Therefore, there is a risk of propaganda: 'spin', if you will, and no doubt those persecuted may have genuinely believed in the divinity of Jesus.
I don't think they were insane: I suspect they were at best misguided and at worst misled. In any event 'insanity' implies mental illness, which I doubt you are qualified to diagnose (especially in relation to people who have been dead for around 2,000 years).
I think the risks of mistakes or lies regarding in the anecdotes about Jesus are such that the key element (he died and was resurrected) isn't a serious proposition.
