I would rather be killed than spend even 20 years in prison. Technically I might live another 20 years, but I would be very near EOL at that age. Could I get the choice?
If the only argument in favor of the death penalty is that the prison system is inhumane, to the point that someone would rather die than go through it, the answer to that should be to make the prison system more humane.
Death isn't categorically inhumane. There are many circumstances in life that I would choose death over survival. It's barbaric for you to force me, against my will, to keep going through such things.
