Ive recently mauled the farm people, the guards, and one of the khajiit caravan members near Solitude . Now there was a reason, I literally "stumbled" right into the middle of the Solitude entrance area whenever I was still in werewolf mode. But my question was after killing most of them, do they ever respawn? Not that I want to kill them again but I kind of like having cities that are lively with people.

General rule of thumb:

If it has a proper name, it probably won't respawn.

All living things respawn within 30 days unless it has a name.

The guards will respawn. Everyone else, if they had proper names, probably not.

Guess it doesn't matter that much then, I only killed the khajiit that looked like the caravan guard and the farms people at the stables, since all of these people were the only ones attacking me. Along with the gaurds but they respawn.

If you want a

You shouldn't be playing Skyrim then, lol.

Don't think they respawn, if they have a name. If they're just generic, they respawn.
