You are unlikely to seriously injure someone with a single blow. It can happen, especially if you KO them and their head hits the ground hard, but it's not likely to. And your conscience should feel clear on this if it does happen, because they created the situation. Many of my techniques are designed to destroy (elbows, wrists, etc.). I won't hesitate to use them if someone puts me in danger and the technique is handy. Those are very likely to leave a long-term injury, but he was trying to injure me, so I'll do what I must to defend.just curious and sorry to hijack thread.
With all the training that we do, i have no doubt that in a street fight, we can 'lights out' the thug pretty easy. Therein lies my problem.... i sometimes will run scenarios in my mind where i get jumped (though likely not, being a safe jurisdiction, and i keep out of danger zones), and instinct takes over and i land a 'killer blow' to either the head, or ribs, severely injuring the thug. (Concussion, broken ribs etc). Honestly i will feel damn guilty if i accidentally killed someone, or even severely injure anyone... am i the only one feeling this way?
(or i could be way overestimating my abilities, lol)
