It could be worst because in some countries they would have given him the death penalty.
How is death penalty worse than life in prison?
I can't say 100% that it is worst. I think that is up to the individual. However quite a few people on death row would rather have life. I remember one of the guys executed in the Bali nine was asked what kind of life would he have in prison. He responded that it was a life. I would probably not want to sit in a cage for life but my decision may change if faced with death.
