Many kinds of early-in-life medical interventions can have permanent negative effects if they go bad, but nonetheless our ethical standards don’t preclude them. This is a field where the ethical standards are suffocatingly high without good reason. As an aside, we should consider euthanizing newborns who suffer debilitatingly severe negative side effects due to any kind of failed medical intervention (with parental consent, of course). This will directly improve life standards and also allow us to lower ethical standards on experimental treatments too.
