Hands chopped off for stealing and being stoned to death for committing adultery are "fair" punishments for crimes committed in Saudi Arabia.

Yes, i do support it, for murders and such.

No.
Innocent people are executed all the time.
Think about that. A guy gets convicted for something he's never done. Spends years on death row. Then he gets strapped to a stretcher, feels the needle with the poison being injected into his arm, and knows that his life will now end.

Imagine if that was you.
If that happened ONCE because of a policy then it would be unacceptable. And this is something that happens regularly in countries with the death penalty. There are organizations in the US that frees innocent people from the death penalty all the time.

So fuck no on the death penalty. Not only is it not ethically defensible if the justice system was 100% accurate, but when you keep convicting innocent people, that seals the deal.

Yes, humans aren't precious.

Yes. Easily.
I'd rather be offed than spend rest of my life in a cell like a rat.

Never. Not even for the most evil, unrepentant person.
As surely as the headsman's axe dulls with every swing, so too is a person damaged with every life they approve of taking.  An axe can be sharpened, easily restored, but people are not so easily fixed. 

So you are in favor of murder, if it is a murderer that you kill?

If humans aren´t precious, why are you in favor of the death penalty? :)

Yes.

Yep.
