I recently watched the Kill Bill movies. In Vol. 2 in the texas funeral scene Beatrix Kiddo is buried alive with a flashlight. But I don't understand why Budd gives Beatrix the chance to see something when she is buried alive. If he want that she suffers he could use the mace. As for myself I think he wants to give her a little chance of survive and get the possibility for revenge. Because in a scene before Budd says to Elle Driver:
Budd: That woman deserves her revenge and we deserve to die.
Is there any evidence why Budd gives the flashlight to Beatrix before she gets buried alive? Or another good question could be: is Budd 100 % sure that Beatrix is going to die?
