So if he makes a different decission it's randomness? That doesn't make sense to me, he made a different decission.
If you reverse time to just before the robbery, he'll probably (but not surely) do it again, as the circumstances will be 99.99% similar before the robbery. If you reverse time to several days before, the robbery probably won't happen. This also ties with chaos theory, a small change has huge effects on the long term.
That doesn't mean it's randomness though. There is a complex system behind it, humans are making decissions all the time and those decissions affect the system, which affect other decissions. Of course those decissions are going to be influenced by society, one's upbringing, etc., but all those factors are also made by human decissions.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
