Can somebody tell me why my camera script isn't working?

I’m making a remote event that when you activate it and put a bool value that is true, the camera turns into a sort of 2D platformer game camera. The problem is that, after activating the remote event with the value true, then later activating it as false, it still does the 2D camera.
(local script) Code:

game.ReplicatedStorage.CamFollowPlayer.OnClientEvent:Connect(function(thing)
	local player = game.Players.LocalPlayer
	local camera = workspace.CurrentCamera
	camera.CameraSubject = player.Character.HumanoidRootPart
	camera.CameraType = Enum.CameraType.Attach
	camera.FieldOfView = 40

	game:GetService("RunService").RenderStepped:Connect(function()
		if thing == true then
		workspace.Cut.Position = player.Character.HumanoidRootPart.Position + Vector3.new(20, 0, 0)
			camera.CFrame = workspace.Cut.CFrame
		end
		if thing == false then
			print("yeah it's false")
		end
	end)
end)
