I would say she was "wrong". The people that misused her work, pushing for a ban before the science was in-place, share her new title as one of the greatest mass murderers in human history--(a million and a half dead a year for 34 years, with many more blinded and otherwise disabled).

"There never was any scientific evidence that DDT posed a risk to humans or wildlife. An EPA administrative law judge said as much after seven months and 9,000 pages of testimony about DDT in 1972. DDT wasn’t responsible for the decline in bald eagle populations, didn’t cause bird egg shell-thinning and [...]didn’t cause cancer in humans, the judge determined.

DDT was nonethless banned in the U.S. when then-EPA administrator William Ruckleshaus reversed without explanation the decision of the judge who actually heard all the DDT testimony – Ruckleshaus heard none of it and never read any of the transcript. As it was later revealed, Ruckleshaus was a member of the Audubon Society and raised money for the Environmental Defense Fund – the two activist groups that led the charge for the DDT ban.

She is as guilty of the ninety million deaths from malaria as if she had personally shot every malaria victim in the head.
