Ok, so, here’s the thing:

We know that a person’s mind has a lot to do with their bending. People, especially water benders, need to think of what they are bending, exactly. I saw a post regarding Hama when she sucked the flowers dry. A person asked why Katara wasn’t dehydrated. The simple response in that Hama wasn’t trying to suck the water out of Katara, only the flowers. The same can be thought of when Katara uses her and Toph’s sweat to break out of the wooden cage. Clearly the bending mind doesnt try to bend EVERY piece of water, or ever piece of earth, or every flame, or every bit of air. It needs to aim. THe bender needs to think.

The second and probably most important point to what i am saying is metal bending.  All it took for Toph to metal bend was for her to think of metal as earth and not as a different thing. Her mind and the way she thought was the only way she was able to do it. Mind over muscle.

Next we can look at Aang. His thought process when learning Earth bending shows this. He doesn’t understand it. He cant put in in his mind that he can bend the earth. His mind, of course, ruins his bending for him.

The same thing happens to Zuko. When Zuko changes sides, he is unable to bend the way he did because he  thought differently. It took going to the dragons for him to get his fire bending back. It took a new way of looking at fire bending.

So, whats this got to do with Amon? Well, its all about brain power. He is the leader of the chi blockers. IE he IS  A chi blocker. Being their leader, he is probably the most powerful chi bender. So, if he can do something that disables a person;s bending for say, a few days, or maybe a week, that could mess with their heads. It has been proven that if a person believes htye cannot bend, they cannot bend. Look at Korra. She cant Air Bend, not because she physically cant, but she is not in the proper Air Bender mindset.

So think of it. Amon uses a powerful chi blocking move on people, telling them hes energy bending. They believe it. They try to for a few days after it first happens, but they cant do it. Remember the Guru? He talked about Chakras. If they are not cleaned, bending stops. He blocks their chakras, and they are unaware that they can unblock them. THeir believe they have no bending forever, and because they believe it it is true.

We know this is how bending works. Its more menat than physical, which is why Korra has such a difficult time with it. She’s a much more physical person than Aang ever was. That’s why she has an issue with Air bending. Its the most mental of them all. Aang knew it was mental and not physical, which is why he had such a hard time with Fire. Its the most physical of the bending.

Amon is messing with people’s minds. Theres a saying that goes: People will believe something if its a) something they wish to be true, or B) something theyre afraid is true. If you fear something so much and you think it happened to you, it happened to you.

Just think about it. They never say that Sokka died. Just that Katara “lost her brother” Could it be? Is it possible? I would hate to say that Aang and Sokka eventually became enemies, but teenage friendships can turn into that. Sokka could, potentially, have become a chi bender, no? I mean, Ty Lee joined the Kyoshi warriors, Sakka was banging a Kyoshi warrior. There’s a VERY good chance he could have learned it. Clearly Ty Lee taught people how to chi block. THIS IS INTENSE.

And I’m assuming that the story Amon told was a lie, thought there is a chance his face was burned by a fire bender. Maybe even Zuko.
