I am disabled, two back surgeries and in pain all the time,and if i were in that situation i would probably take the first blow, but not sure about the second. That said heres how it goes.....Do you really want to take someones life over a punch? and do you have tens of thousands of dollars to afford a defense attorney? Do you really want to set in jail for months before a trial? And what about your wife and you kids? Do you have the means to support them as you set in jail without you supporting them? Guys its a decision you have to live with the time you pull that trigger, So Please! Make it a wise one! All lifes will change forever! Just make sure it worth it!
