Btw, why do you think they're maniacs? Most Enclave soldiers want to remake USA, and i don't think they want to kill everything on sight, they have orders. And also you can remember the end of Fallout 2, when you can speak to Enclave soldiers and they will fight with you against Horrigan. Most members of Enclave just want to have better life, they're not maniacs who has a dream "Me want kill all humans!".
