Usually I will measure the worthiness of life with the other party when encounter commotion/violence.
If the other party is worthless, better not get into deeper shit and use ah q mentality to avoid.
If is a learned well groomed person, my life is not as worthy as his, I will not give chance.
So have to make very quick "life worthiness" decision and react immediately.
Your method is fucked up and for cowards and useless fucktards and ah Qs.
Champions go into every fight looking to win.
Assess ki lan.
The only time if any to back off is when you're outnumbered and/or not on form.
