It also goes into why anyone would die for the belief if they knew it was false, as thousands would have seen Jesus before and after his death to know about it, while the various Apostles and disciples would have been able to save themselves from horrible torture by just telling whatever authorities who had them that they were lieing. Apparently one of the Watergate people became a Christian because he looked at that and was amazed that people wouldn't rat each other out if it was all a lie,Ah yes, I've read the passage you're referring to. It is quite a shocking text! For that reason. Although of course the intended implication was that they weren't all wrong about what happened.
Anyways, stupid decisions... We are talking about things only stupid in hindsight, or stupid with what they knew at the time? Columbus would have been pretty stupid with his journeys due to the distances being wrong (and him claiming the Earth was shaped like a pear) but some suggest he had a good idea something was in sailable distance due to the driftwood that washed up on the Canaries. I also thing the Danes giving up Norwegian islands to Scotland as a dowry was pretty stupid, if we are going by hindsight. Imagine the fishing and oil rights. A,so would have made the Faroes much more closely linked to Denmark is the Shetlands were Danish. Then again, the English, Scottish, British, etc would have probably taken them at one point anyways. Though maybe they would stick to grabbing Man, the Orkneys, and the Hebrides.
