Nor would you be able to prevent a man spilling tea on his suit, taking it to get cleaned, getting assassinated for it as he was notable, a rally cry from his family, and an ensuing civil war.
If you want to look at it as simply numbers and forget about any immersion or imagination as to how a situation arose, then that is your sad loss. Me? I would look at it as quite unfortunate and make my choice in a way to minimize the damage. Ruling a Kingdom shouldnt be easy. It shouldnt turn into a cake-walk as soon as you have a single fortified castle. Right now, I go to my town, load up on troops and I can take 3-4 castles without sweating on Maxed difficulty without any support. More than that, when you are sitting in town training troops or managing your fiefs in person, things should happen, and not always good. IMO if you aren't going to have 'bad' events, there shouldn't be any good events because the game is easy enough as it is without many good ones.
P.S. Guess what, the good ones are randomized too.
I am not saying make the game impossible to play for lower difficulty players, but I am saying that not everything needs a bright and shiny ending. There needs to be catastrophe, plague, disaster, and betrayal. There needs to be ways to reduce the damage, but not always a way to remove it. Politics are a dainty dance of death, where the main goal is to manage to give yours orders and use your powers without finding your head on a plate.
