At the scale that google is at, is the exact the reason they need to be hold accountable for any misconduct because the impact is so big. If google just display third party content only, then yes, users need to use their own judgement. But if google itself generate content instead and put out claims, due to it's scale and reputation, those content needs to be true because most of the people put trust in Google, so any untrue or false information especially defame others, Google is 100% liable, period. You clearly don't have the clear mind or mental capacity to analyze this situation, probably very slow.
