[Stargate Atlantis] Why didn't they bring a sarcophagus with them to the Pegasus Galaxy?

So we know from SG-1 that the sarcophagus technology can lead to your personality becoming evil with heavy repeated use of the device, probably in the hundreds of times. This why the Tok'ra don't use it. We also know that you can get somewhat addicted to it (Ba'al torturing Jack).

But for one-off fixes of cancer or mortal injuries or other diseases, why not have an emergency sarcophagus?

For the same reason they don't have one at Stargate Command for the same purposes.  It's took tempting and too addicting.  Once you start using it, even for emergency situations, you're going to keep using it.
