The one that hasn't suffered any deaths yet. The one that screws LOTR townies over more and more every night, simply by virtue of its continued existence. Killing is the only way I can reduce LOTR townie numbers, but LOTR cult can, has and will do so via conversion. Meanwhile, you can't reduce LOTR cult numbers without a night kill power, which you can only gain through co-operating with me. Once I'm dead, your only recourse will be lynching and you can't reduce the numbers of an expanding cult with that alone. You might be reluctant to let me live because you think you might be a target of mine. But look at the situation from my perspective - who would I be looking to kill tonight? Obviously, a LOTR cultist. They are the biggest roadblock in the way of my continuing existence, and presumably have kills up their sleeve. It doesn't make sense to worry about me killing you if you vote for spaceman.
I'm not asking for trust, as we're not on the same team. I'm asking for something mutually beneficial, given the particular situation we find ourselves in this round.
I'm fairly sure "we will get to killing the LOTR cult tomorrow" has been the refrain for the last four days or so.
