Tylenol itself is not toxic to the liver, the metabolite of glucuronidation is what is toxic. Which means paradoxically impaired liver function can actually reduce the effective toxicity of Tylenol.

I mean, sure, but the most important part you left out: "if you take 4x the recommended dosage, or take it consistently beyond the recommended period of use".

Lots of drugs are toxic if misused or abused. Acetaminophen is not unique in that regard.
