"Murderer"
The process to accomplish things Godfather could not do after his death also took a long time, longer than his entire life, because he died at such a young age of less than forty years old.
He was only in his thirties, still at his prime, and if he became powerful, he could still extend his life to several hundred years.
However, those few hundred years were spent in a spirit state instead, and those enemies lived a comfortable life until such an old age.
Thinking again, maybe he should never let those people die so easily!
But they were already weak, and they would not be able to resist the tossing of torture within just a few hours.
So...maybe they died a justifiable death.
