Let me clarify what I originally was getting at.
I saw the first three guys as ENTp-Ti (pretending that they were completely normal people, and that's the type that seemed most fitting).(VA-Tech not as sure about, the only reason I thought ENTp possibly was after watching the video of him saying what he had to say). Now, given that these were/are NOT normal people, but instead psychologically disturbed individuals, I was very curious to see how someone of ANY type could go wrong like that, and given that one or two I think may be my identical, I was particularly interested to see how they can take a mindset of an ENTp and turn it so bad, so negative, and distort reality to try to rationalize their actions.

Yes - the positive qualities you mentioned are what an ENTp SHOULD be. That is a NORMAL HEALTHY ENTp. BUT, what about the unhealthy, disturbed, distorted, pathological ones? Could these be examples of the type going bad to the extreme?
Here's a possible thought I had. Is that they can use Ne in destructive ways to figure out possibilities for inflicting damage, and when they feel that they aren't accepted, they use Ne Ti to unhealthily rationalize unthinkable actions (again being disturbed individuals - NORMAL unhappy ENTps would never do this).
In other words, I was particularly interested on what different things would cause different types to rationalize such horrific actions. I'm curious as to how an ISTj would rationalize doing something like that and how it would be different as to how an ENTp would rationalize it for example, still keeping in mind that each would still have psychological disorders.
