First i live in switzerland, no death sentence here, for the story, here last few years we got a guy who raped a girl and got 6 years of jail... than got out, found back the girl raped her again and killed her....
Sorry but guy like this should just die !
For me there is 3 case where the death sentence could apply :
1) More than 2 murder (i don't talk about self defense)
2) Rapping girl on purpose.
3) Pedophilia
BUT, i would prefere a system where the guilty work every days for 15h for the society all their live ! i personnaly would be more afraid to have no hope to a better live than a you just gonna die....
Here in jail, you can have TV (i know i refused to do army for personal reason).... i mean common its almost some vaccation...
