There is a mechanic in the game known as the Stalemate detector. It comes in and ends the game early if there is a situation were the game will never end and gives the win to someone (Eg. Mafioso and Escort alive, Mafia wins. Mafioso and Transporter alive, Town wins. Godfather and Transporter alive, Mafia wins).
In this case, there is absolutely no chance for Town to win. Even if you successfully kill the Werewolf with your alert, you still die in the process. Therefore the game automatically lets the Werewolf win, as it is the only role with a chance to win in that situation. This is not the case with Serial Killer and Arsonist, as you can kill either of them and still live and win the game for Town.
