California has some of the most violent prisons, and violent people in the country, where on going wars continue between Mexican gangs, black gangs, outlaw biker groups etc. The most violent of the violent.
It's my guess being humanely executed would be the easy way out, as opposed to living in these types of institutions for life. Facing life in these violent madhouses, I'd rather be executed if given a choice.
By the way, I favor the death penalty, in many cases.
The death row inmates are kept in separate prisons for the most part. I think if we can kill them maybe we could convince the nuts in government that it would be for the prisoners own good if they were put on a vegan diet and forced to do yoga every day for the rest of their lives in their 4x6 cells.
Exterminate them like cockroaches. Clear out all the guards and then accidentally release some Zyklon B. That would save the taxpayers a whole lot of money, even though the ACLU might get upset.
