There's obviously no way of telling. However, most criminals avoid murder - it's messy, people get all upset. I was in martial arts for a long time, the first thing they tell you is that you don't want to fight. You want to run away unless you have no choice. So, you learn to strike hard and fast at multiple targets. This gives you space and then you run, preferably throwing your wallet or some cash behind you. Nobody typically carries a week or even a month's salary as they wander about. Dead is really dead and the only priority is to get out. That kind of attitude is very different than trying to not be robbed, which is much more likely to get you killed. In the first case you could argue he had to fight this guy because OP was hanging around watching the action. If I'm with some guy with combat training and somebody pulls a knife? I know he can take care of himself, I'll toss whatever valuable in my pockets out there (always wise to keep cash outside your wallet in rough area) then run like the devil was behind me. Even if he's as fast as me, I've got adrenaline and the lead from him grabbing the cash. lol why I am writing so much I do not know...
