Why is does the Bloxxer die everytime he destroys a Sheriff?

So I have this Murder Mystery-Like Code, but the Bloxxer (the character with the sword) dies when he destroys the/a Sheriff. The section of code I believe is malfunctioning is the part that ensures the Sheriff doesn't kill the bystanders; but if Sheriff does kill a bystander, the Sheriff dies immediately. However, these same parameters seem to be happening to the Bloxxer also, Why?

I want it to work so if the Sheriff bloxxes someone other (a bystander) than the Mad Bloxxer then the Sheriff dies. I also want the Mad Bloxxer to remain alive even after he destroys a Sheriff in order to destroy the bystanders.

I don't want the Mad Bloxxer to be destroyed when he destroys a Sheriff.

Now here is the suspicious section of code:

function newCharacter(bloxxedPlayer, character) 
	local humanoid = character:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.Died:connect(function()
			if bloxxedPlayer == sheriff then
				humanoid:UnequipTools()
				local backpack = bloxxedPlayer:FindFirstChild("Backpack")
				if backpack then
					backpack:ClearAllChildren()
				end
				local torso = character:FindFirstChild("HumanoidRootPart")
				if torso then
					dropNetGun(torso.Position)
				end
			end
			
			-- This section determine whether the person bloxxed was the Mad Bloxxer or a bystander, if the latter then the sheriff dies.
			local tag = humanoid:FindFirstChild("creator")
			if tag and tag.Value and tag.Value.Parent == game.Players then
				if tag ~= bloxxer and bloxxedPlayer ~= bloxxer then
					print(tag.Value)
					local wrongDoer = tag.Value
					if wrongDoer.Character and wrongDoer.Character.Parent then
						local wrongDoerHumanoid = wrongDoer.Character:FindFirstChild("Humanoid")
						if wrongDoerHumanoid then
							wrongDoerHumanoid.Health = 0
						end
					end
				end
			end
		end)
	end
end

The problem was line 20.

I was checking for 'tag' instead of 'tag.Value.' I changed 'tag' to 'tag.Value' and it fixed the problem.
