I am against the death penalty out of principle, not practical reasons. It goes fundamentally against rehabilitation, its effect differs from person to person drastically, it's just weird and vengeful. And making exceptions for edge cases is not good for a justice system.
So what if you do this instead: consistently enforce, say, 10 year prison sentences for murder as a CEO. This kind of stuff would stop overnight. But that doesn't happen unfortunately.
They can try all they want. I see that occasionally on the websites people sell their stuff on. But usually even those people are willing to sell for a reasonable offer if their ad has been up for a long time.
