@n3f_X All mammalian predators follow the same basic heuristic:

1. If it's running away it's prey.
2. If it's running at me it's a threat.

Predators can not afford to be injured and lose the ability to chase down and subdue prey so they are generally very risk-averse when it comes to threats.

As a general rule for any predator you outweigh your best bet is to charge at it, not away from it, because the algorithm they all follow is to assume anything bigger that acts like it can take you out is probably correct.
