User blog comment:D.Ryan/Is Sander Cohen dead?/@comment-939754-20100404023635

It's absolutely not that easy, I'm sure. For one, it was locked to Ryan's DNA. Why didn't Fontaine use it? Because he was a con artist just bent on control and rushing that goal beyond all others. He did not have the intelligence to do so. If it was as easy as putting his DNA in a single chamber and hitting Reset, you'd think Fontaine would have figured that out and done it. But he's not that smart, and Cohen is even less.
