I find life valuable too. That is why I think if you take it without just cause you don't deserve to live. Even being in prison and in solitary for 24 hours a day eating only stale bread and water would be too good for such a person. The sad truth is some murderers live better then some of our veterans.
The problem with the death penalty to me is the chance of it being done to someone who is innocent. But to me every case is different, so if you have a murder with a bunch of DNA evidence and the person even admits they are guilty of the crime..I don't see any reason they should spend 10 years in the system before they get put down.
If someone has a legitimate case for an appeal I am not against that, but I would want some kind of evidence or valid reason to go forward with such a thing. There are such a thing as clean cut cases. These people don't need to be in the system for 10 years.
I know what I say next will be controversial, but to me prison should be something that you'd actually rather get executed then spend your life there. At least when it comes to murderers. So I am not saying treat low level criminals horribly, but personally I wouldn't want to spend life in prison if I was in solitary 99% of the time and only got bread and water..which is what I think should be done to killers. I believe in rehabilitation for criminals..the ones who deserve it. Murderers deserve nothing.
If you're going to keep them in prison forever then make it as shitty an experience as possible. They don't need to be watching movies or reading books or working out. Maybe give them a picture of the person they killed to stare at.
