Old-school Alison may have been a net positive for the Church, but latter-day Alison wasn't.
But later day Allison gave it all up to bring Mendicant down... That easily makes the top 5 of Allison's best hits. Number one might be kicking Aram out of the church, then auto da fe'd him. Then my RP about looting his wine cellars as the peasant followers burned down his estates.
