it doesn't even look at the smaller picture. LLMs build sentences by looking at what's most statistically likely to follow the part of the sentence they have already built (based on the most frequent combinations from their training data). If they start with "Hitler was effective" LLMs don't make any ethical consideration at all.... they just look at how to end that sentence in the most statistically convincing imitation of human language that they can.

Guardrails are built by painstakingly trying to add ad-hoc rules not to generate "combinations that contain these words" or "sequences of words like these". They are easily bypassed by asking for the same concept in another way that wasn't explicitly disabled, because there's no "concept" to LLMs, just combination of words.
