"Yeah." Senku agreed. He'd studied his history, he knew all about it.

"I have no interest in introducing certain concepts back into the world, but I expect that me having control over the situation is going to eventually not be the case." Senku answered, completely realistically.

"If by some chance I did have some modicum of control as to what science path people follow or don't? I still can't stop progress. People get ideas, terrible ones at that."

He sighed. "The only solace someone can take, is that usually with the worst possible things that humanity has done, the worst science you can think of, it always leads to the progress of the good too."

Just because he was somewhat ethical, didn't mean everyone would be, and he knew that. He also recognized he may not have control over that forever.
