This has been bugging me ever since I saw "A Man Alone". Some funny genetics are found amongst the skin flakes of a murder victim's room. Bashir then clones the genetics to see what it is. Fair enough. But even when he realizes it is developing into a humanoid (and a fully grown one at that), he continues the experiment until there is a fully adult clone living and walking around. Is creating a new lifeform as part of a crime investigation really all that ethical? Especially considering this person will have a drastically shortened lifespan, and will have to learn even the most basic things. Yet no one seems to even remark on this.
