It's not important to me and I'm not into making this a religious debate. I'm fine with your belief and live my life like it's the last one.
That's what my original comment intended. We are on the same page, here.
Isn't locking up people also wrong? Or are we more right in doing the second wrong when death is not involved?
Well, yes-- but there are degrees of "wrongness", it's not a simple matter of 100% or 0%. Except in the case of state-sponsored killing, of course.
There are even degrees of being locked up: minimalist facilities that are more of a country club you are not permitted to leave, through various increasing unpleasantness up to the most brutal things humans have created (although not intentionally in the case of hard-core lockups).
It's not all or nothing.
Is there any actual evidence for that, though, that those facing death penalty will act worse?
Yes. I'll not insult your intelligence presuming you cannot find out for yourself, however.
I'd expect there to be a possibility to have such penalties reserved for higher confidence. It's not like laws aren't man made, that they couldn't be further improved to differentiate between cases where there is for example a large group of surviving victims and witnesses, video evidence as well as catching the perp red handed.
Well, yes-- hypothetically you would appear to have a valid point. Except: Have you seen the movie Avatar? Or perhaps any one of the latest Marvel movies?
Video "evidence" can be hacked, altered, edited, adjusted, manipulated in such a way to appear the exact opposite of what it is supposedly "evidence" for....
As for witnesses? They are the absolute worst of the worst, when it comes to evidence. No two people see the same thing, even if they were standing side-by-side as disinterested witnesses.....
My point is this: IF a system can become Corrupt, THEN it is possible to manufacture ANY evidence the system requires, to do What It Wants.
And we know from history, that ALL government is corrupt to some degree-- and since we do not have an actual participatory Democracy anywhere on the planet? (All are indirect, Representative, and all use a formal Judicial System for crime and punishment) It is safe to assume ALL are corrupt, at least a bit.
With Corruption, comes the most heinous crime of Punishing the Innocent for the Crime of Someone Else.
I find I cannot abide the thought of even ONE such example--ever.
In contrast to the U.S.S.R, wherein you really could walk down Moscow streets at 3 am with money hanging out of your pockets, and you'd be Okay-- so long as you did not run afoul of the Party (naturally).
Their motto was: "We may kill an unfortunate innocent or three, but by damn, NO criminal EVER gets away!" (parenthetic: unless they are Party-- then? Anything Goes)
