LightWolf lynching HD would have at worst ended up in his redirecting the lynch back to you anyway. The fact that you gained a mayor vote and a redirect if he ever used the lynch redirect made you the best role the village had at that point (because we knew all of the mafia DLE was mostly useless).
In other words there was absolutely no downside to lynching someone else. Either that person is Establishment and we get a free lynch or you happen to lynch a DC Villain and we end up at worst right back where we started.
Losing the IRS and a Mayor vote very nearly lost us majority (we only had an advantage of about one vote the last day).
YOU LOST NO MAYOR VOTE, the only one who lost a mayor vote when I was lynched was the wolf not us. And I already HAD the redirect, that wouldn't have been a gain.
Redirecting the lynch back to me would have been the BEST result actually, I'd rather have died than our OUTED VILLAGE HOOKER. Sorry but no, outed village hooker would have been the one offed not me. The fact I was announced village leader with two confirmed and outed villagers around, should hint at my usefulness. Really trading a hooker for a mayor is not the best trade in the world.
And yes we knew every mafia at that point BUT we didn't KNOW that we knew every mafia, from our point of view we had too few suspects to make up TWO mafia teams, no one suspected at that point that there was only one mafia. As far as we knew, DLE was still useful. And in all honestly, my redirect was fairly useless, we knew no roles bar the pope's which made barely any sense at the time, I had literary nothing to redirect at that point, my role was just as pointless as DLE's just we actually knew we did not have anything even at that time. And I also had no vote before the lynch redirect, say they hit the hooker, we lose a hooker and a vote, gain 2 votes and the mafia loses two, our net gain would be 3 votes worth of advantage. Now in the self lynch case, with my death we lose no votes, we lose IRS vote (which we are not guaranteed to keep, since he is a neutral, mafia could convince him to vote for them at any given time) and mafia loses two, net gain of 1 vote for us, but we lost no hooker! And considering the likeliness of me dying the following night if I didn't lynch myself, the gained votes would be gone, putting us at a 0, whereas in the case where I get lynched the next death would also bring us to 0 differences. No difference in the end, minus a living hooker still being protected by the BG.
Basically controlled loses always are better than letting the enemy call the shots. I'd rather sacrifice myself rather than let a mafia act upon whatever info they had. At that point it seemed like if we pick between the suspects we are likelier to hit DC and DC was likely to have ways to gather information. At that point they may have know our BG but what ever happened they knew our hooker for sure. I sacrificed the leg of the village instead of letting the mafia possibly take it's heart.
