There are potentially other things he could have done (considering he is now dead, he clearly chose a path that led to the worst possible outcome). But I am not going to be an armchair quarterback and say that it is obvious what he should have done.
People under duress do not act rationally in many cases. It isn't fair to blame someone under extreme duress for making a err in judgement and becoming a victim as a result.
There was a case of a young girl being hounded by Billy Eichner for a show called "Billy on the Street." This girl was simply asked to "name a woman", but was unable to actually name one, because she was put on the spot and her confusion/anxiety increased as Billy became more belligerent (which is kind of the point of the show).

Does this mean the girl is stupid? Or does it mean that people can really struggle to do the rational thing when dealing with stress, whether small or large?
I don't care if he made the wrong move in trying to get away, because he was being put in a ridiculously stressful situation and I can absolutely see that stress leading to him making a mistake. I don't think anyone here without any kind of training could reasonably assert they would react better.
