Round 1

Preventing diseases by editing embryos is ethical as it prevents future suffering for the child, in return giving them a better chance of having a desirable life without having to worry about their disorder or issue. Ethicality is established through how the childs life will improve significantly to an extent depending on the disorder.

In 2017, a CRISPR study on human embryos carrying a heart-muscle mutation found the correction was often incomplete and sometimes caused large unintended deletions around the target. That's not a hypothetical risk. It's the core problem: you're permanently altering a future person who cannot consent, using a tool that still makes messy errors. The other side is right that inherited disease causes real suffering. But we already avoid much of that with embryo screening and donor eggs. Editing adds a new irreversible step without a clear medical need. That's why I don't think it's ethically justified yet.

The information that you described in the study is incorrect as that specific study actually described the mutation as being succesfully corrected with no off-target effects detected. Furthermore, In research targeting the MYBPC3 gene (which causes the heart condition hypertrophic cardiomyopathy), researchers achieved a 72% to 72.4% success rate when introducing the CRISPR-Cas9 machinery simultaneously with fertilization during IVF. That rate of success should justify the need for embryo editing and the ethicality of it.

CaseStudy_CAGAINST
In the only known births from edited human embryos, He Jiankui's 2018 twins were mosaic and carried unintended edits, not a clean correction. That's the whole problem in one case: the child gets a permanent change nobody fully controls. My opponent says editing improves the child's life, and inherited disease is real suffering. Fair. But clinics already prevent many of these diseases by screening embryos or using donor eggs without cutting DNA. Editing adds irreversible risk for a benefit screening can often deliver. Until the errors are gone, "ethically justified" is too strong.

Although screening can work for many, there are many instances where screening has failed and it is too generalizing to say that screening can often deliver when in many cases it fails to deliver. If a healthy embryo cannot be produced, than screening fails entirely. There is an 100% failure rate of screening if these factors are in play: homozygous dominant disorders, two affected parents as both parents every single embryo will create an affected child. For these families, the alternative is not screening, it is a complete denial of biological parenthood. Editing is the only tool that can prevent the passing down of mutations in these cases.Even when a healthy embryo is statistically possible, IVF is a game of attrition. Many couples struggle to produce more than a few viable embryos due to age or fertility issues. If a couple has a 50% or 75% risk of passing on a disease, screening and discarding affected embryos drastically reduces their already slim chances of a successful pregnancy.Discarding viable but affected embryos drives couples into repeated, physically demanding, and financially draining IVF cycles. Editing corrects the embryos they do have, maximizing their chances of a successful pregnancy rather than throwing scarce embryos away.

The real question isn't whether preventing disease is good. It's whether we should permanently change a future person's DNA when the tool is still unreliable. My opponent cites a 72% success rate, but in medicine that means roughly one in four embryos doesn't get the intended result. And success in a lab dish isn't the same as a healthy child, as the He Jiankui case showed. Screening and donor eggs already avoid many of these diseases without cutting DNA. Until editing is near-error-free, calling it ethically justified puts the experiment on someone who can't consent.
