One other thought - If you get into serious trouble points-wise, don't be afraid to betray. Looking at the chart, you can never lose points by betraying. You won't gain anything, but you won't die either.
I feel like that point is going to become important.
When I say you won't gain anything, I mean that you probably won't gain anything, because people will become more reluctant to trust you, so unless you get lucky with your first try, you'll probably get stuck in a betray/betray loop.
