Hypothetically, there’s no immediate option to escape a person who has attacked you and is intent on causing you further harm. Do you think you would be able to fight back and create an opportunity to escape? Do you have a plan for if things go sideways and you end up on the ground with them raining blows down upon you? Can you fight to survive until your last breath?
It’s a difficult situation for sure. The only solution is to overwhelm them with violence to create an exit.
