Congrats on picking the most extreme example possible.
What about a situation where someone kills their wife after work one day? How will you know if he had thought about it for a while or just snapped? Obviously you will look at the evidence and see if there was clear evidence of planning or not. But if there's not how can you be confident in whether it was planned?

I never said we know in every instance. And the death penalty isn't applied in every instance either.

Right, and in this court can choose not to execute him based on this uncertainty.

Good, because it doesn't.
