I wonder...wouldn't killing the pope generate some fairly negative characteristics for the general in charge of the conquering army? I mean 'Pope-killer' must have been a pretty serious vice in medieval Europe; even now it's probably not the best route to making friends and influencing people. I haven't quite got my head around the full ramifications of the vice/virtue system in MTW, but have noticed that when I've been excommunicated my generals' acumen and command ratings tend to nosedive after a few turns (maybe it's coincidence, maybe I just didn't read that manual closely enough).

Having said all that, 'Pope-killer' might be rather a good thing for your assassin - he could dine out on that for the rest of his career. I suppose what I'm trying to ask, in rather a drawn out way, is this: do any special vices/virtues develop as a result of bumping off the supreme pontiff, which don't occur when other world leaders get the grassy-knoll treatment?

Any advice gratefully received...
