It's not though? People aren't doing fact-checking out of kindness, they're doing it because they're being paid to do it. The people paying them expect a certain outcome from their fact-checking activities, and objectivity doesn't really factor into the picture, but ensuring a certain narrative prevails, does.

Pretending that a news story is factually correct because someone is getting paid to check it for accuracy is asinine. The fact checkers themselves have biases and aren't objective sources of truth, same with the people supplying their paychecks.

The fact that people have the capacity to lie and be violent, but that not everyone is a liar or a murderer is obvious and doesn't need to be stated.
