Where is the line between gamethrowing and metagaming for a victory

[GoatseOntheCupboard]

I've been seeing a lot of people host these really terrible "cult vs masons with minimal night kills" saves and here's what tends to happen in them:

Town ships the only killer, or entire (usually 2man) triad really quickly, or they AFK and heart attack out of game

Town now has scum hopelessly outnumbered, and confirmed ML + confirmed mason starts bashing cultists every night. There's no killer that can hurt the confirmed ML, and when the auditor audits a mason the new ML just masons him again etc etc

Host is a retard and left "1 night between conversions" off
ML is bashing a cultist, townie helps find another cultist that is bashed, becomes confirmed, gets converted

Game ends with 6 dead cultists in graveyard AKA 6 townies that lost the game by getting culted then bashed by ML (and usually either the most helpful or most "confirmed" townies

The two masons and maybe 1 town win the game together

Since the majority of the town-starting players actually lost the game, why don't I either:
Find a cultist then suicide immediately after as a non-mason townie to cement my alignment as townie and win when the cult dies OR
Get a townie or 2 to vote with cult, and Lynch the mason leader while I am town, assuming that the cultists will convert me

Am I playing for my wincon or my alignments wincon? Because I would act very differently depending on what's gamethrowing. Also don't post PTFO or you'll be banned
