^ Youkai are dead already as mentioned multiple times in the anime. However, they can enter a state of 'death' (if you can call it that) where they become husks if enough trauma, physical or psychological, is made. But they can come back from this state eventually on their own accord.

So Ash's Pokemon don't exactly have a way to kill Nate's Youkai besides disabling them I guess?
