Here's the plan: First we get captured...

This seems to be one of the most common plot devices for espionage and sci-fi series episodes and movies. Why don't villains recognize that their plans for global/galactic/universal domination would almost always succeed if they did NOT capture their opponents? There is a near 100% probability that they will escape and find the nuclear self destruct button or functional equivalent. This is greatly assisted by corridors in their starship/skull cave/headquarters that are designed to allow maximum concealment and recruitment of henchmen with very restricted vision.
