Krieg
Krieg, the Psycho, is a Vault Hunter who suffered horrifying experimentation at the hands of Hyperion Corporation. And while the process made him much stronger, it also drove him to insanity not unlike many other psychos in Pandora, with only a fragment of his former, saner self now acting as a conscience to him. With that said, Krieg's inner self is well aware of everything he does, and is nearly unable to do anything about it.
