The Tests in Fallout 2 were not crazy. They were mostly mild social experiments, with the worst one being a faulty vault door to study the effects of prolonged heightened radiation exposure. Which, under the background of potential interstellar travel, made kinda sense.Well before the retcon of the show, I thought all of the crazy tests the Vault-Tec folk were doing were for the Enclave with the latter being the setting's ultimate big bad.
Yeah, I wouldn't make that comparison. "Native Americans are drug dealing raiders who engaged in constant unprovoked atrocities against the United States." That's not a sentence I'd want my name associated with.
The Great Khans aren't without sympathy but they're a criminal gang first and foremost.
I mean, the crazy tests weren't made by bethesda. They were made by Fallout 2 and gathering information for the Enclave. While the Fallout Bible is no longer canon, things like the broken door on Necropolis and other "tests" were done for people other than Vault-Tec itself.
So these contractors were directly answering to the people ordering them about.
The whacky evil experiments came later.
