Because my kill will fail anyway - it's strategically optimal to take any anti-town abilities away especially when the cost to me is losing a failed kill for no kill at all. Not "triggered" either. Why am I asking for a Curfew if I'm Serial and need people to die? As Serial, the sooner town dies the better because that would mean they reach a point where they can't afford to remove me, at the same time I'd need enough scum dead to avoid being endgamed so a Curfew is the worst thing that can happen for me.
Neither you or Ekko are capable of thinking what you say through though, all you do is jump at the lowest of hanging fruit and stick with it. Probably why the Town is so awful this game actually.
