When the humanoid dies, it returns a message 4 times even though the humanoid died once?

So I was creating a killfeed that involved a RemoteEvent, ServerScript and a LocalScript.

Everything was working fine, but the killfeed template was cloned 4 times... Isn't the Humanoid.Died function supposed to fire once?

Here's the ServerScript inside the ServerScriptService:

game.ReplicatedStorage.TakeDamage.OnServerEvent:Connect(function(player,damage,hum)
	if hum then
		hum:TakeDamage(damage)
		hum.Died:Connect(function()
			local cooldown = true
			if cooldown == true then
				cooldown = false
				print('killed')
			game.ReplicatedStorage.AddKill:FireAllClients(player.Name,hum.Parent.Name)
			end
		end)
	end
end)

Here's the LocalScript inside the ScreenGui:

game.ReplicatedStorage.AddKill.OnClientEvent:Connect(function(killerName,victimName)
	local killfeedLabel = script.Parent.KillfeedTemplate:Clone()
	killfeedLabel.Parent = script.Parent
	killfeedLabel.Text = "<"..string.upper(killerName).."> KILLED <"..string.upper(victimName)..">"
	killfeedLabel.Visible = true
	wait(3)
	game:GetService("TweenService"):Create(killfeedLabel,TweenInfo.new(0.5),{TextTransparency = 1,TextStrokeTransparency = 1}):Play()
	wait(0.5)
	killfeedLabel:Destroy()
end)

Sorry if it's hard to read...

I tried to find any article I could find, but I did not find any helpful. Any sort of help is appreciated!
