Mafia 102. Veliria

They are the same. Moreover, the second one was specifically about the one that kills Neutral creatures, and not just any "type (U)". At least, that's how it seems more logical to me...

Then why did you ask about the difference between plus/minus and the regular "U"? And did you ask if it's possible to ask a question not about a specific type of Neutral creature, but about a group of "killing" Neutral creatures?
