If you think so, what sources would you recommend? According to Wikipedia on medical ethics, "These values include the respect for autonomy". Not expecting any level of self control doesn't show respect for autonomy IMHO.
Interesting. I'll look into that. The Hippocratic oath says that a physician should do no harm (ἐπὶ δηλήσει δὲ καὶ ἀδικίῃ εἴρξειν). It's a personal value judgement as to whether some intervention is providing medical care or causing harm. I consider reckless genetic modification to be causing harm.
