It is every animal's instinct to either fight or flee in this scenario, this response could depend on various factors including size of the attacker, how threatening they appear, and so forth.

If one bear attacks another bear, they will fight to death. If one spider encounters another spider, they will fight to death. If a rabbit encounters a coyote, the rabbit will flee, because it knows it cannot fight.

Humans are no different.

When one of the many street animals in Toronto attacks a hardworking man doing his banking, it is the man's natural instinct to fight, and it is disgraceful, in fact possibly even a human rights violation to punish the man for acting on his instincts. Instead, the woke politicians just bitch about human rights of some nutcase who says they are not sure if they if they are a man or women.

Happy this man dealt justice to that scum.
