On my last playthrough I sneaked up to a hill at the edge of the camp using the forced turn based function and shoved one of the scout goblins to his death with my main char (i separated him from the others who were at another location entirely), with no witnesses, succeeded with sneaking roll and all but the whole camp still turned to hostile. Reloaded and tried it several times but every time whole camp was turning to hostile.

It felt disappointing because i was able to spot a good opportunity (there is one point when none of the vision cones reach him and he is standing next to a pit basically). Not sure if its intended or just a bug.
