I believe that it is morally permissible for the researchers to use gene therapy, even though they knew they ran the risk of some patients developing cancer. I say this because, even though the outcome could be cancer for some patients, the overall outcome would have been greater than not doing a treatment that could potentially help the children have a working immune system. If they were to not perform the treatment on the children because they new that the children may get leukemia after, then the children would still end up dying at a young age. I feel as if you never know if a treatment will have risks involved. As any treatment may cause risks because people react different to all treatments. You are better off performing the treatment
