1. When you arrive at Nipton you see what the Legion is capable of for the first time. They've crucified people and put heads on steaks. One of the leaders tells you to look around and basically see how corrupt the people of the wasteland are. I did, and what I found was surprising. If you read the mayor's computer terminal he goes into great detail about how he is using people, making money any way that he can and has plans that are motivated by greed. Add that to the fact that the Legion had given out lottery tickets to the townspeople, who then proceeded to become animals and fight and stab one another in the back to try and escape, disregarding any care for one another (even women and children). The Legion put the townspeople of Nipton in a situation to show their true character, and selfishness and violence was the result. The winner of the lottery (forgot his name), was a perfect example of the corruption of the townspeople of Nipton. He was ecstatic about his "luck" and could obviously care less about the fact that every other person in the town, "loved ones" or "friends" were killed. All he cared about was himself. Now that's just one example.
2. The Legion does not allow any addictive drug use, kills those who use them or drink alcohol.
3. They focus on prosttutes, and their main goal is to "cleanse the wasteland." It is a fairly noble goal if you ask me. Are innocent people killed in the process? Well, is anyone truly innocent? At least that's the claims of the Legion and I have to agree. Most of the people of the wasteland are selfish and will stab you in the back the moment they get the opportunity to take something from you.
4. If you look at the actions of groups like the NCR, many of them are hypocrites. On one hand they are the "good guys" and on the other they are partying, drinking and buying prosttutes on the Strip. You don't see any of Caesar's men doing this.
5. And my last point. The world is in the state that it is in because of selfishness and greed. The Legion is attempting to cure the world of such things. Drastic times calls for drastic measures.
Legion all the way!
