Strap 'em to the chair.
Lethally inject 'em.
Firing squad.
I don't see how the method matters as long as it gets the job done.
The big problem with capital punishment is that the politicians are scared to utilize it because We the Sheeple whine and piss if it's not our loved one who was victimized by these scum. It's not expensive to execute some rabid human; what's expensive is the never ending legal process.
We cry and moan about prison overcrowding and the expense of incarcerating all the scum, but I could fix that pretty quickly. I'm not sure why we spend our money caging humans who will never be anything other than violent insane shitbags. Put ALL violent criminals to death, then there will be plenty of room for the thieves and non-violent criminals. Wanna end the for-profit prison system? Put their violent insane guests to death.
But we read too many Stephen King books, where everyone in prison is innocent and a great guy. That's why everyone in the world except me loves Shawshank Redemption and Green Mile - I dislike the romanticizing of scum. I've never watched one second of OITNB because I know I'll hate it. I didn't think Jax was hot, and I didn't think Walter White was cool. I didn't like Tony Soprano or anyone on that show - in fact the only reason I kept watching was to see all those disgusting scum die. I don't root for bad guys, I want to see the good guys win even though they're boring and dumb compared to the charismatic bad guy.
And that's just the tip of my rant. I have a whole freaking months long diatribe about how We the Sheeple have been conditioned to root for bad guys. I could write a book. A series of books. A series that would make GoT look like a Little Golden book.
