Haven't read the thread but here's my pitch on it:

The justice system isn't perfect, innocent people do get wrongly convicted sometimes. It may be reletavly rare but I don't think the odds will ever be low enough when you're gambling with a life.

If you believe in an after life then fair enough, you may feel that death is the begining punishment... but if you don't then a relativly painless death is little punishment compared to a life sentance.

I believe that those guilty should have to exist for the rest of their lives, not living - in punishment. If there's no afterlife then they've been punished as much as possible withouyt physical torture... if there is an afterlife then not only have they lived their mortal life in punishment but now eternity.

I do understand that a lot of the victims may want death to get closture, but if the prison system is right (which tbh it's not) then I'd rather have them existing and suffering then at peace.
