Fallout: 10 Most Evil Companies 

Before the war, RobCo, founded by Mr. Robert House in 2042 was the world's leading manufacturer of combat robots and other technologies. They created the protectron, the sentry bot, the eyebot, stealth boys, and more.

Unfortunately, RobCo also had many projects in the works that were purely horrifying. One notable example is the company's partnership with General Atomics International and the U.S. army to create the robobrain: the first robot using a human brain as it's main computer.

The robobrain's brains came from U.S. citizens and military personnel who almost certainly didn't know what they were getting themselves into. After their brains were removed, the "donors" were forcibly stripped of all personality and memory by careful brainwashing and turned into simple automatons, able only to respond to orders.

There are many more examples of RobCo being pure evil, such as their venture with Hornwright Industrial and Atomic Mining Services to completely bulldoze Watoga National Park and replace it with a company city where all the residents are basically owned servants to the RobCo facility on site.

Not to mention they made Liberty Prime. A literal nuke throwing behemoth that the U.S. in Fallout planned to use against its enemies.
