If you went up to lvl 3 and eliminated 2 raders at entrance, and then talked to Gorsky you could tell @there were people but I helped them@ when in reality you didn't.
On the other hand, if you befrend with raiders, you can say "there are people held hostages and we need to help them", but only in that case.
I think you should be able to tell that in both cases, and to tell "I helped them" only when all raiders are eliminated.
