I consider myself a pretty aggressive person. Sometimes the red vision overrides common sense in my case and gets me in trouble. That said, I don't presume to know how I would act in a certain situation until it actually occurs. I lift heavy weights and used to box, I don't find any one person particularly scary, but that said, if somebody pointed a gun at me, would I freak out?
Who knows. Maybe, maybe not.
My grandfather said that while fighting in france and germany in WWII that you didn't know who was going to be the brave one on the battlefield. The little mousy f**kup in boot could be the superheroic drag you out from behind enemy lines type guy during combat, and the toughest meanest mofo in boot, could be the biggest sissy when the fighting occurs. Sometimes it'd even change from battle to battle. Human nature is such that its only constant is its unpredictability.
