Setting aside the obvious issues of comparing a country with a population of 30.8 million to one with a population of 331.9 million, a low estimate of casualties in the American Civil War is around 600,000. About 100,000 people died of drug overdoses in total last year.
So, no, fentanyl is not killing people more people than the Civil War by literally any metric.
The irony of you ranting about our collective unwillingness "to ask for forgiveness when we cause harm" combined with your description of transgender health care as "mutilation" is overwhelming.
