When does scientific research become unethical?
When it causes, or is likely to cause harm
When it is forced
When it is coerced
When it is used for the purposes of control
When it is "scientific" in name only, ie: relies on some unproven bias
When it is done to further a falsehood: ie: AZT for AIDS (a falsehood), "vaccines" for Covid-19 (a falsehood)
When it is used against those who cannot consent and/or are easily coerced: infants and children, the mentally disadvantaged
When it is funded for any of these reasons
