Blaming the thief 100% completely negates any personal responsibility of the owner, which is a very dangerous line to toe.
Rephrase the situation like this: There was no thief, but an escaped zoo monkey got into the car, managed to start the ignition and drove into a river, drowning in the process. Or if that's too unlikely, let's just say he took a dump and smeared it on the wind shield. If you want to make it more gruesome though - let's say the owner left his dog in the car, said monkey opened the door and the dog ran under the bus.
In all of those you now have a 100% "the owner is at fault" scenario. The only difference is that in your hypothetical scenario the other party is presented as more negative than the first, which somehow absolves the first party of any guilt, which is simply not true.
The only truth of the matter is that crime will exist. It existed since the inception of humanity and might as well be the only constant until the heat-death of the universe. So yes, personal responsibility is a huge factor if you want to assign blame in these scenarios.
