Class Tension?

Class today had a lot of discussion in it, and I think it got a couple people a little heated.  The question of "Was the selling of Henrietta's cells ethical?" was a very intense one. Personally, I could see the argument of both sides, but I may lean more towards one. I see the argument that it was just a few cells and it isn't that big a deal seeing as it didn't harm Henrietta. On the other hand, I believe it is morally right to just ask her, seeing as it is her body and her cells. Also, HeLa became so successful and helped so many people, and her family had no idea. They had no idea that Henrietta was helping discover so many things and help so many people. If my mother died I would like to know if she still lived on and contributed to so many discoveries. They were also being selfish because they didn't want to share their profit with anyone. So I guess in the end, I believe it was morally right to tell them, and they should've.
