Infinite guards

A problem I have with this game, just like with pretty much all other games is that there is an infinite amount of guards. Example:
In Sasau my reputation went to -100 (because of a bug) and guards started randomly attacking me without me having a bounty and after that happened a few times I decided to kill them all so they don’t bother me again.
I killed maybe 20 or so before they stopped coming, but then I walked around the corner and there’s two more, I avoid them and ride through the city to my destination and the guards are patrolling in their usual numbers mere seconds after I killed what should be nearly half of them.

To make a game more realistic the spawn-rate of guards should be much lower, if I kill all of them there shouldn’t be any patrols at all for at least a week or so. How it is now makes the game oddly similar to Skyrim.
