Cho received his post-mortem glory, which possibly could encourage others to do the same thing. Most psychos live a relatively pathetic lives and then die. However if they know they can become larger then life in the media by killing as many people as possible before cashing out then we'll end up seeing more and more of them taking that option in the future.

Information and videos of him like this COULD MAYBE MIGHT give us more insight into someone who would do something like this. Maybe someone out there can recognize this behavior in someone else and get that person help before it is too late. (Though all I saw was a weak man with severe psychosis, and his idiot ramblings seem evidence of a gross detachment from reality ... not the "hero victim" he may have wanted). But it does seem excessively pointed just to him...

AND YES. I want more about the Professor, heroes, the guy that saved himself tourniquet!!

I'll shut up, I am noticing my own rambling as I try to come to a decision about this...
