The very worst horror that could face you for the rest of your life, is if you weren't able to do the 'right thing' when the lives of your wife and children, for example, were snuffed out after terrible atrocities with you as a helpless witness. This can happen at home or when out and about.
Why should you think of this? Simply because you are studying a martial art. Ask yourself the real reason why you took up martial arts and be honest with yourself.
So with this 'settled' …keep in mind the word 'foreseeability' and visualize you being able to do the 'right thing' by your family.
What are the chances of anything horrible happening to any of us? But what if it does happen, as it happened to my family with a child shot in the head by home invaders?
We often analyze scenarios from a legal perspective, in order to determine when it is appropriate to shoot. By thinking through the issues in advance, we eliminate or decrease any hesitation that would occur during the incident if we were considering those possibilities for the first time. While we usually use a 'legal' framework, it is still really a 'moral' question. A lot of the emotion that you must overcome is related to the rightfulness of your decision to shoot. To that extent, emotion can be minimized by doing your thinking in advance. This addresses at least one issue: fear of consequences (whether by God or the courts). Other issues (e.g. fear for the safety of your family) are more difficult.
The 'being armed' plus the proper training and the mental conditioning, as per above, may well lead you to do the 'right thing' in a moment of human bestiality.
Consider this…Gabe Suarez
I recall one event back in the 1990s. there was this three man crew of Bounty hunter Bloods...a gang based in 'The Jungle" in Los Angeles. They specialized in very violent home invasions.
Anyway...this crew drives up to an affluent area of town and invades a home. Not a hard thing to do since the stupid liberals kept their front door unlocked, hated guns and actually invited the nice gentlemen from the inner city inside.
Once inside they raped the woman in front of her husband and kids, pistol whipped everyone and stuck a pistol in a little girl's mouth to coerce the parents to give up the cash.
To make a long story short, we caught up with them on Eastbound I-10 and engaged in a pursuit. This was totally against policy since my partner and I were in plain clothes in an unmarked car (albeit code three capable). Those of you, who have lived in LA, imagine a Friday Night at about 1900 HRS driving into the downtown area.
Speeds topped 100 MPH. Eventually another unit caught up to us and took over the pursuit, but we were not about to back off so we stayed. Eventually the bad guys exited the freeway in some parts of town that even the police did not go to. And as we careened over people's lawns, through alleys and split traffic, we lost both our rear view mirrors and most of the paint on both sides of the car, a very nice undercover Mustang as I recall.
As they are wont to do, the bad guys crashed their car in some backlot and began firing at us as they ran away and we closed in. They were armed with Glock 21s.
I recall opening the passenger door as my partner put the car into a sideways skid to avoid hitting the barriers. I was out of the car before it stopped moving, my sawed off 870 in hand. I remember running toward three figures I could make out because of their white t-shirts and their muzzle flashes. As I brought up my 870 and began firing...
Now imagine this 'on your head' for the rest of your life and the lives of your family.
