Last hand a Mistake?

[tarantulabob]

First of all, thanks to all who've responded and encouraged me this evening. I think I did alright. 8th out of 321, not that it means anything as it's winner take all.

So, did I screw up had I lost all my chip on? Few hands into the final table, no real reads. The big stacks are aggressive, actually everyone seems to be somewhat agro, but that's due to size of the blinds i suppose.
