 For many, the fact that reproductive cloning is unsafe provides a sufficient reason not to pursue it. It has been argued that it would simply be wrong to impose such significant health risks on humans. The strongest version of this argument states that it would be wrong now to produce a child using SCNT because it would constitute a case of wrongful procreation. Some adopt a consent-based objection and condemn cloning because the person conceived cannot consent to being exposed to significant risks involved in the procedure (Kass 1998; PCBE 2002). Against this, it has been argued that even if reproductive cloning is unsafe, it may still be permissible if there are no safer means to bring that very same child into existence so long as the child is expected to have a life worth living (Strong 2005).
