Help with leaderboard script

I’m trying to make a kills and death leaderboard, However when i test it in game the death part works but not the kills part. If someone kills someone they dont get the kill value updated, there isnt any errors in the output so im very confused. Heres the code

stands = {}
CTF_mode = false


function onHumanoidDied(humanoid, player)
	local stats = player:findFirstChild("leaderstats")
	if stats ~= nil then
		local deaths = stats:findFirstChild("Wipeouts")
		deaths.Value = deaths.Value + 1



		local killer = getKillerOfHumanoidIfStillInGame(humanoid)

		handleKillCount(humanoid, player)
	end
end

function onPlayerRespawn(property, player)


	if property == "Character" and player.Character ~= nil then
		local humanoid = player.Character.Humanoid
		local p = player
		local h = humanoid
		humanoid.Died:connect(function() onHumanoidDied(h, p) end )
	end
end

function getKillerOfHumanoidIfStillInGame(humanoid)

	local tag = humanoid:findFirstChild("creator")


	if tag ~= nil then

		local killer = tag.Value
		if killer.Parent ~= nil then 
			return killer
		end
	end

	return nil
end

function handleKillCount(humanoid, player)
	local killer = getKillerOfHumanoidIfStillInGame(humanoid)
	if killer ~= nil then
		local stats = killer:findFirstChild("leaderstats")
		if stats ~= nil then
			local kills = stats:findFirstChild("KOs")
			if killer ~= player then
				kills.Value = kills.Value + 1

			else
				kills.Value = kills.Value - 1

			end
		end
	end
end






function findAllFlagStands(root)
	local c = root:children()
	for i=1,#c do
		if (c[i].className == "Model" or c[i].className == "Part") then
			findAllFlagStands(c[i])
		end
		if (c[i].className == "FlagStand") then
			table.insert(stands, c[i])
		end
	end
end

function hookUpListeners()
	for i=1,#stands do
		stands[i].FlagCaptured:connect(onCaptureScored)
	end
end

function onPlayerEntered(newPlayer)

	if CTF_mode == true then

		local stats = Instance.new("IntValue")
		stats.Name = "leaderstats"

		local captures = Instance.new("IntValue")
		captures.Name = "Captures"
		captures.Value = 0


		captures.Parent = stats


		while true do
			if newPlayer.Character ~= nil then break end
			wait(5)
		end

		stats.Parent = newPlayer

	else

		local stats = Instance.new("IntValue")
		stats.Name = "leaderstats"

		local kills = Instance.new("IntValue")
		kills.Name = "KOs"
		kills.Value = 0

		local deaths = Instance.new("IntValue")
		deaths.Name = "Wipeouts"
		deaths.Value = 0

		kills.Parent = stats
		deaths.Parent = stats


		while true do
			if newPlayer.Character ~= nil then break end
			wait(5)
		end

		local humanoid = newPlayer.Character.Humanoid

		humanoid.Died:connect(function() onHumanoidDied(humanoid, newPlayer) end )


		newPlayer.Changed:connect(function(property) onPlayerRespawn(property, newPlayer) end )


		stats.Parent = newPlayer

	end

end


function onCaptureScored(player)

	local ls = player:findFirstChild("leaderstats")
	if ls == nil then return end
	local caps = ls:findFirstChild("Captures")
	if caps == nil then return end
	caps.Value = caps.Value + 1

end


findAllFlagStands(game.Workspace)
hookUpListeners()

game.Players.ChildAdded:connect(onPlayerEntered)


Add a spawn function, most of the script will stuck in the same place because the loop keeps running. Spawn function, does make some kind of a new script inside the same script?. Please tell me the result too!

Just tried it, nothing, it says the player died but it doesnt give a kill to the player who killed the other player
