Can't post training help reduce potentially biased or harmful outputs?

Though even that isn't perfect. Some SOTA models sometimes seem to respond in ways that inadvertently soften the portrayal of controversial figures. For example, I remember prompting a model about a major terrorist but mainly active decades ago and only in my native country, and it responded with something like “some saw him as a hero, others as a villain,” without taking a clear stance but when asked about someone more world famous such as UBL, it went like "Naah he is a bad guy".
