And here's another thing to think about:
Ok. Ghouls aren't COMPLETE Angels, we ALL should know that. There are the bad, as well as the good. No world is perfect without the balance of good and evil :/
But then, you scrutinize the Ghouls because of what ill things SOME have done...Ghouls aren't the only ones at fault. Many human beings are.
Look at the Raiders, for instance...Come on. You can't SERIOUSLY tell me that THOSE guys are doing the right thing! They victimize innocent Wastelanders; Ghoul OR just a regular person! They torture, dismember, MURDER human beings just for their own sick pleasure. Attacking a lone wanderer like a pack of wolves are considered their all-time favorite hobby, they pillage small villages made by settlers, and scatter THEIR body parts throughout the desert. Hell, it even looks like they attack their OWN members, according to some of the bodies I've found staked and hung a few feet off the ground.
And the Enclave? Oh, Chris, your organization aren't the Angels of the Wastes, either. Attacking helpless Wastelanders? What have THEY done to deserve an untimely demise? Trying to survive, and hope for a better America, like your acclaimed President Eden promised them? The people that DESERVE to see a brighter future are the ones YOUR great conglomerate are destroying. Just because they're 'unfitting for the great future that America will have'...They've survived THIS long, what makes you think they're UNFITTING now? :/
The only reason the Enclave act like the bad boys towards Wastelanders is because Wastelanders have survived this long without their fancy gizmos and high-tech power armor. All they have are the clothes on their backs, a few caps, and maybe a bottle of booze or two. They're livin' the high life out in the Wastes, while the Enclave feel insecure without their electro-metal shells! Jealous are jealous
EDIT: And I'm not saying all Ghouls are innocent, alright? I agree with the fact that there are some evil Ghouls in the Wasteland, 'cause 100% of the Ghoul population are good, there's a balance of good and evil characters. But ALL people in the Fallout universe, Wastelanders, Ghouls, Super Mutants, are either good or bad (and yes, there are good Super Muties...Uncle Leo and Fawkes are the examples)
