Bangladesh considers death penalty for rapists.

[Aegon]

Doesn't matter what the crime is. If there's even a small chance that the justice system prosecutes the wrong guy and sentences an innocent person to death, there should be no death penalty. Period.

Go one step further - 

What if you incarcerate an innocent person?

Many people think prison is worse than death.

Should we just scrap the penal system?

Well, I have quite a bit to say about the American penal system in particular, but... if you don't already see the astronomical difference between the state wrongfully sentencing a man to 10 years with parole vs. the state wrongfully ending his one, only life on the planet Earth, I doubt I'll be able to explain it to you.

I can accept the state's power to imprison. However, whether we the people should permit the state the ability to legally kill as punishment for a crime is an entirely different discussion with different philosophical considerations.

I'm against the death penalty always.

I think prisons should be humane always. To this end they should be run by the government not a corporation!

Humans are worthwhile from an ROI perspective so even those that should not be free can be useful.

We should exploit them for labor like we do now.

This would give us the opportunity to release a wrongfully incarcerated person as well as get use from properly incarcerated people.

Prisons should be both humane and exploit prisoners for labor? How are you reconciling those two ideas? Exploiting prisoners for their labor is quite literally legal slavery. Don't believe me? Give the 13th amendment another read.
