That's almost exactly what happened to Pol Pot, except he didn't even go to prison, just house arrest.  Though he did only kill his own people.

I am for this of course, but as Ned Start said: "The man who passes the sentence should swing the sword"

Statistically, having a death sentence does not reduce cases of crime. (The correlation is very slightly in the opposit direction). Prison is not torture in all parts of the world - european nations largely continue to treat them as people, prisons serving mainly to rehabilitate criminals (with surveillance of psychiatrists), and keepimg them from doing any harm untill the treatment is over.

even for a criminal, I do not see the point of doing any harm soley for that purpose. Northern Europe shows that it is very possible to have low crime rates with mild punishment, in that case, why not?

Many people have been found innocent after spending many years on death row. In fact just recently (I think his name was Glenn Ford) was found not guilty after spending 30 years on death row and was just weeks away from execution. Yeah, DNA is one hell of a defense.

There is no peace without war or death.

We can do without the personal attacks while debating, thanks. 

It's just about the same as a comfort inn but with bars. haha

I've been told that it's a slippery slope, inhumane, and could lead to active pursuit of inmates (as in, finding any possible reason to put a person behind bars) if private prisons get involved, but instead of the death penalty via injection, chair, or whatever, I say experiment on them.

I'm talking about the serial killers, child rapists, etc. The worst of the worst. The people who do it simply for their own enjoyment. That drug that the FDA is too afraid to put to trials? Put it on these inmates and see what happens. If they die, well then shit, they were on death row anyway. If they don't die and we can validate any sort of results, then we've just cured AIDS without spending billions on clinical trials and waiting years to put it into the market.

"But that it gross. That's torture". And how do you think the 8 children this guy beat and raped felt? You know, maybe criminals should learn to feel a little empathy for their crimes. You know that scene in Family Guy where Peter is in prison and the inmate promises to stab Peter, and at the end of the episode, he stabs himself and says "oh, that's what that feels like? I probably shouldn't do that anymore".

I know prison should be about rehabilitation and not revenge, but some people just can't be rehabilitated.  And in those scenarios, at least make their heinous crimes lead to something good.

Makes you wonder why 99% of the population hates prison life if this was actually the case. There is delusion in the words typed out by you and the person you quoted, and this is fact so don't try and tell me that I'm just being hateful. Prison life is well documented to change people (for better or worse) and to take the engaged existence out of their well being. Unfortunately - due to people putting words into other peoples mouth - I need to explain that I'm not saying certain people can change and should be set free just pointing out that any amount of jail time causes introspection, which may be worth nothing in the end, I can admit.

Not many people can say they are comfortable with seclusion, even fewer are comfortable with forced seclusion. You can list off all the "great" things about prison life but your narrow-mindedness shines like the sun when you don't even consider the environment, the "tasty" food, the people that each separate jail possesses and the list goes on. Its not a pleasant place to be, its depressing, empty. You guys are making it seem like all these guys do is activities, play video games, hang out and have quality time...these things are not in abundance in fact prisoners are limited to a short period of time.

Tipping ones scale so heavily to one side - no matter the manner - is not very fruitful, in fact its counter productive because the only way to tip your scale so heavily on one side is to remove perspective that may take form against the other side. Doing so leads to skewed and useless results.
