Just an FYI, using the Knock Out option instead of Stealth Kill will reduce the radius of who gets alerted to the kill. If their beds aren’t too close to each other, you can sometimes Knock Out one sleeping bandit/Cuman/whatever without waking anyone else in camp, pick up his body, carry it far enough from camp that you can dump it, stand up, and Kill him without alerting the entire camp.
The Gravedigger perk helps with this as you travel faster and don’t use stamina while carrying the body.
