Are we going to measure things by who got most sick or by who got the most out of it? Because if Midgley gets sick and his boss who knows everything gets a million dollars, I will blame his boss more.

For example Charles Kettering (essentially boss of Midgley) was Director of Research for 27 years at GM. Was large shareholder of GM. And he hired Robert Arthur Kehoe to prove that TEL is safe. And Kehoe did. The "proof" was that "you didn't definitively prove that TEL is unsafe, so it's okay".

Btw Kehoe is also the one who certified that Freon is safe.
