That things keep going may be evidence that God is an optimist, to not get ticked off and roll it all up.

One of the things that hasn't been stopped is the injury sequence, where someone is injured because somebody else was injured and the injured person wants to, consciously or unconsciously, pass it on. And so creates another injured person.

God, the possible optimist, may look at a person formed a certain way by injury and feel that a person of this shape could be a unique tool to do something good and generous that wouldn't be possible for someone who wasn't injured in that way.

So the messed up get the assignment that they are capable of doing, and they do it or they don't. Attempted unusual generosity is a more pleasant way to spend time than passing on injury.
