Why does this loop?

This seems to loop for no reason

workspace.DescendantAdded:connect(function(a)
	if HP.CodeLock==true then
	wait(1)
	if a.ClassName=='LocalScript' or 'Script' then
		for Plr in pairs(game.Players:GetPlayers()) do
		wait(1)
		Tablet('Institutional white','ClassName ['..a.ClassName..']',Plr)
		wait(1)
		Tablet('Lime green','Disable ['..a.Name..']?',function() a.Disabled=true end,Plr)
		wait(1)
		Tablet('Lime green','Allow ['..a.Name..']?',function() a.Disabled=false end,Plr)
	end
	end
	end
end)

By using the "for" "do" it creates a for loop.
