I think he should get a life sentence to protect people from him. I don't think i have the right to chose if this guy must live or not.
here is the trick to it... you said "you don't have the right to choose" but HE is making that choice for others. He is deciding if anyone lives or dies. That right of his must be taken away. A life sentence is typical for murders but at what cost? Did you know a lifer is anywhere from $70,000-$120,000 a year costs dependent on the criminal? So life (only 25 years in the US and Canada) will bring a minimum cost of $1.7- $3 million dollars IF he gets out after 25 years which some of the hard core offenders serve indefinatly. Based on his age he could live 50 years in prison bringing up the cost to $3.4-$6 million to hold him.
Take that number now and multiply it by the number of all the murders in prison right now either sitting on death row or serving life sentences (or close to it)... All this money could be used for other things. Making schools safer, better, stronger. Making hospitals safer, better stronger. Making our economies better, safer stronger. These "killers" take every one down with them in terms of society costs.. The cost of supporting criminals could be used in the search to cure cancer, cure aids, cure your herpes, cure whatever! A quicker more extreme justice system needs to implemented. I would suggest starting with killers. I would be shocked if anyone would disagree.
