If Guns were Legal in the United Kingdom, would this stabbing be prevented?

A random teenager in the UK was set up to be stabbed and chased for blocks by two other boys with swords. In my own opinion that kid would still be alive today here. Because in the US we have a rule here called force meets force, so the fact these guys have deadly weapons on their persons, it is equal to administer lethal force. Therefore a gun owner can come out defend themselves and that young boy running for his life & the two criminals would be taken off the streets for good. Instead of the innocent kid, who was mistaken of the wrong identity. 2A (2nd Amendant) saves lives.

If guns were legal in the UK would that young boy still be alive?
