How would you feel if you discovered that investigators had taken cells or tissues from some member of your family without consent?

Personally, if my cells were taken without my permission, I would be enraged. Not only do I not know what they are using them for, but without consent? It just does not seem right in my opinion. Then, if something were to happen where my cells and or tissues become important enough in society, I would not know what to do. It just is not the right thing to do to take cells without proper consent and use them for your own purposes. However, if they were using them for a cause that would benefit me or people I knew, I would not be as frustrated. However, there is still no justifiable way of taking something that does not belong to you, such as the aforementioned cells and tissues, and then using them for your own means.
