Did your opinion about equating/similarizing scientific research with 'toying with things' increase or decrease (or stay the same)? Just my opinion, but my suspicion is that someone smart enough to do research would have to either directly consider or consciously set aside the (frequently culturally specific) moral implications of their work, especially in the life sciences fields, to be able to get anything done.
Through history, scientific research has always conflicted with someone's sense (at least on the fringes) of right and wrong. These are what you, the newest member of your family, and all of us are confronted with for our era. They aren't easy questions.
P.S. Congratulations, by the way.
