what does cootie think about the reason that hela cells were used to develop a polio vaccine ?

Being that Henrietta helped Cootie while he was sick with polio, he understood that her donation of cells was for the good of everyone.

“She used to take care of me when my polio got bad,” he told me. “She always did say she wanted to fix it. She couldn’t help me cause I had it before she got sick, but she saw how bad it got. I imagine that’s why she used them cells to help get rid of it for other folk.” He paused. “Nobody round here never understood how she dead and that thing still livin. That’s where the mystery’s at.”
