Tuskegee syphillis experiment
No. In my opinion this is far worse.
First; the victims of the Tuskegee experiment at least had some responsibility for their illness.
Second; the Tuskegee experiment was small scale.
Third; the Tuskegee experiment had a valid scientific value.
Forth; the Tuskegee experiment was not performed with the expressed consent of and legislative act of Congress and the President.
It went on for 40 years. No one ever held responsible, no one went to jail.
Same thing is happening again.
