The supermutant base isn't where you get the GECK. It's an old and destroyed pre-war research lab.If you read the lab records, the experiments were all destroyed. Obvioulsy the supermutants can't transform humans into supermutants.
Australian customs: Do you have a criminal record? Me: I didn't think you needed one anymore.
They can transform humans into supermutants. In the vault where u get the geck Fawkes tells u about it, and thats why she was locked up, cuz she didnt agree with what they were doing its also the same reason uncle leo is just walking around the wasteland
Good or bad doesnt matter. Bad gets taken out by social law, and good gets taken out by murphy's law.
