There are fates far worse than death, and for me being locked up in a cage for the rest of my life would be far worse than knowing when and where I was going to die.
As for the death penalty I am for it. I believe that if you commit a crime that is henious enough you should be put down, just like a rabid dog would be put down.
The only issue I see in the way that the death penalty is used in the U.S.A. is that it does not seem to be the same way for all people ie. more blacks receive the death penalty than whites, woman are almost never given the death penalty even though some are just as deserving, if not more so than there male conterparts.
Now I don't think that the death penalty should be imposed like it is in China where you can be executed for things like drug abuse, or government officials excepting bribes.
