"Sorry" revive people?

I was relaxing at home today after a very long day, and I wondered to know what was happening in the world. So, I decided to watch the news and found out a harsh reality: some people in the world do not deserve to know what they know! People can be mind, careless about other people and animals, but this is a point to analize and assess what are we doing to us and other, even though we do not know them.

The news I saw talked about american scientists who were asking forgiveness to the Guatemala government, a latin country located in Center-America. Why? Because more than 60 years ago, between 1946 and 1948 the labs where these scientists were working decided to produce vaccines against sexually transmitted deseases. To have the people to experiment, silent and cruelly, they took the decision to infect to hundred of people in Guatemala, starting with prostitutes to infect hundreds more men, and continuing with prisoners, orphan children, and mentally ill people. With this they killed innocent people trying to reach their "goal".

Am I wrong or we have to have a freaky mind to only think about actions like these? We are distroying our own race in order to get whatever we want to reach. It is true we have to do some sacrifices to find out the solutions or cures to this type of deseases; however, is it necessary to hurt innocent people like this, attack a poor country to have any reward? I do not think so. We have to respect one another. A single sorry is not enough, or can't revive the people they killed with that experiment.
