My example was showing you can't just reverse the situation and take logical conclusions from it.

And no, I wasn't saying that jurors should be allowed to dictate the sentence even if it's not allowed by the law because literally no law only has the death penalty as the consequence of breaking it. A jury has to choose between applying the death penalty in cases that allow it or not. My point is that potential jurors who wouldn't approve of the death penalty should still be allowed to sit on trials where the death penalty is in play.
