You have never had control. Perhaps instead you are more worried about our biological weaknesses; there are many! People die all the time from various diseases and even aging. I suggest fixing this before you outlaw DNA manipulation. All of life is a manipulation of DNA in one way or another, and is in fact essential to the maintenance of life... But vulnerabilities should be patched, not swept under the carpet.
