Given that it is MYLO the question is, do we have enough of a read on someone to risk a mislynch or do we No Lynch and let Mafia narrow things down. One less person means greater the odds of getting scum.
However, with a known killing role, a redirector, and a motivator, there is also a risk in NLing. If pie kills a townie, or is redirected to a townie, that's game over. If Ragnar motivates mafia, that's probably game over depending on their abilities. But also if Pie is - for example - a third party killing role, Town can't afford to lynch him anymore meaning we have to hope Mafia takes him out at some point.
All that said, I'm fairly prone to go policy on this one.
