How do i kill the player using ClickDetector?

So ive been trying to make a part kill you using clickdetector by myself first, but all my attempts were unusuccesful

local players = game:GetService("Players")
local ClickDetector = game.Workspace.clickpart.ClickDetector
local clickpart = script.Parent

clickpart.ClickDetector.MouseClick:Connect(function(hit)
	local player = players:GetPlayerFromCharacter(hit.Parent)
	if player then
		local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

		if humanoid.Health > 0 then
			humanoid.Health = 0
		end
	end
end)
