In some cases, yes. We should do the same here in the USA once the value of a person’s theft exceeds a limit based on the value of a human life. There is a number for that based on earning potential and some other factors. Give it a multiplier (maybe ten times the value of a life but that’s for bean counters to figure out) and also consider mitigating factors like we do in homicide cases. Somebody who steals enough to wipe out many lifetimes of hard, honest work may not be directly killing anyone but theft at that scale has destructive and deadly consequences.
Normally I’d say that if you empower the state to execute a certain class of person you can look forward to the state changing that definition so that inconvenient people who did nothing wrong meet it, but I’m unlikely to be mistaken for someone who has committed 10s of billions of dollars in fraud and I can’t help but feel like maybe if just one robber baron is held responsible for the enormous suffering they cause in pursuit of an amount of wealth so vast that it can never be spent and essentially only functions as a high score then the rest will realize that there is the sharp, distinct possibility that they can be held responsible as well.
She can appeal still, and they are doing it as an incentive for her to return 27b. I imagine she will attempt to return a large portion, appeal and then just be given life in prison.
