Anatoly Dyatlov (the man in charge of Reactor No. 4 that night) wasn't that stupid, and it wasn't entirely his fault.

In the reactor there are uranium rods to make the fission happen. There are also control rods made from boron. When Dyatlov gave the order to remove most of the control rods out of the reactor, the few that still remained in it were only slightly inserted at the top. So power and heat were building into a hot spot at the bottom of the core, where the sensors sometimes can't detect it.

No one in the plant were aware of the flaw in the reactor with the hot spot. If they did have, Dyatlov probably would have changed his plans. Sadly, tragically, he didn't.

If you want to see a good documentary on it, I recommend Zero Hour: Disaster at Chernobyl as a good watch. It dramatises what happened in the final hour at the plant from records and eye-witness accounts. Really good stuff.
