You need to read Zimmerman's statement again. He's not describing somone he thinks is trying to kill him. He's describing someone who is actually trying to kill him. There is no subjectivity in his account.
I am trying to be polite but I don't understand why you refuse to address the discussion you started, with your question. You asked what
WE thought, not what Zimmerman thought. I answered what I thought.
As far as cold blooded. Can I get a linky to your definition, just to see if there is anything missing from the actual definition, because I'll be darned if I can't find a single defintion that doesn't include, without feeling or emotion.
Idioms & Phrases
in cold blood
In a purposely ruthless and
unfeeling manner, as in The whole family was murdered in cold blood. This expression alludes to the notion that blood is the seat of emotion and is hot in passion and cold in calm.
The term therefore means not "in the heat of passion," but "in a calculated, deliberate manner." [Late 1500s]

George's perspective is all we have. It is literally the only piece of evidence we have to ascertain what took place during the altercation.
Let me requote your question, again:
Or should we should just consider a cold-blooded murder attempt an act of mundane teenage stupidity as well?
You were asking what we should consider. If you wanted what I think Zimmerman thinks, then ask that.
What information are you talking about? What evidence have you seen that gives you a different perspective on the altercation other than the account Zimmerman provided?
I've tried to explain this already. We know, if nothing else, Martin did not know what Zimmerman was doing because we do not believe in mind reading capabilities. Martin, in the lack of information, is only capable of filling in the blanks with his own imagination, just like Zimmerman was doing. Martin, from what we know, was walking back from the store and a man drives past him, turns around, drives past him again, and then parks on the road ahead of him. As he approaches, the man is talking on the phone and watching every move he makes. We don't need to take an eyewitness account to know that this is what Martin experienced. To know what he was thinking is an entirely different story. All we can do from that angle is imagine what we would think, feel, or do. Which is why I chose the words "my opinion". So based on
my opinion, it is entirely reasonable to believe Martin was afraid. Therefor, his actions (if he hit Zimmerman first) could reasonably be considered defensive, not offensive.
