Scientists as a group hunger for new knowledge. On the positive side, they dedicate their careers to the progress of their respective fields. Their personal traits are dogged determination to figure out why this experiment failed and how another approach might push back the boundaries of the unknown. As a group they exhibit all the worst of human behavior in pettiness and ego just like any other group in any other profession. But at its best, it is filled with the joy and wonder of discovery, passion and commitment to truth.
As we expand the boundaries of what we know, scientists began to push into territory where morality was standing in the embryonic stem cell technology.
Do we destroy existing embryos to find cures?
Do we deliberately make embryos to destroy them to advance the research?
If scientific progress is the end all and be all why not?
