Im trying to make a textbutton that kills you with a cool down. What is wrong?

I only made a button to kill so you get points. but I dont want people to get to get points while being dead. What is wrong?

local debounce = false

if debounce == false then
	debounce = true
	script.Parent.MouseButton1Click:Connect(function()
		wait(5)
		debounce = false
	end)
end

local debounce = false

if debounce == false then
    debounce = true
    script.Parent.MouseButton1Click:Connect(function()
        if game.Players.LocalPlayer.Character.Health <= 0 then
        return end
        else 
        wait(5)
        debounce = false
    end)
end
