A bit of elboration on why the old owner likely wouldn't go to the church about Makoto. People have already touched upon the possibility of illegal activity which is an obvious one, but another would be drawing the eyes of the inquisition to yourself. Gambling and other such things that were going on in the tavern would very much be seen as delvilry by the church who would then ask why such people were drawn there in the first place which will then come back to owner. When the inquisition is doing their rounds, you keep your mouth shut and your head down especially if you have something to hide.
