Easy answer: they aren't evil. There really is no evil, just as there is no good (at least in regards of an evil person or a good person). There are acts that are categorized as being evil or good. But, do you really think the people doing these evil acts consider themselves evil? More than likely, they believe their actions are fully justified. I'm not saying it is right, but I don't think 'evil' people see themselves as being evil. I think putting it in these terms makes it easier to understand how some things happen. There really is no explanation, other than this, for genocide. The people running things see it as necessary for one reason or another. Most sane people, obviously, list such acts as evil and wrong.
In the context of the game, I don't think the back-story to how certain characters became evil is really important. The characters act as one type of protagonist, giving you the option to fight against them or work with them. Same with the Enclave. Is the Enclave evil? They seem to believe their goals will work toward making things better for humans; although, at quite a high price.
There are selfish people though, those that believe their own interests are the only ones needing any consideration. Some may classify this as some sort of mental illness; however, it is possible it is just a very strong survival instinct or some other thing along those lines. It isn't wrong to be self-interested or selfish; although, it doesn't work well within the confines of a society that believes it is wrong or evil to do so.
