Morality

[Rokcet Scientist]

But society had already killed them...

So? The touted 12% of innocents killed were a lot less damaging than the 88% remaining who were

A civilised society doesn't kill people. In the most serious cases you stick them in jail. So that – if it does turn out to be the wrong verdict (again), and an innocent person was jailed for decades and his/her life was irreparably destroyed – society can at least try to rectify the injustice, release the person, accept responsibility and take financially care of him/her for the rest of his/her destroyed life. That would be the decent thing to do. Not doing that is, consequently, indecent !

That's manslaughter, according to the same laws.
That society must go to jail for a looong time!

Laws aren't so because they are moral.

Duh!
They are sold us as serving the concept of 'justice' (ring a bell?). But IRL they of course don't, as e.g. 12% wrongly executed 'murderers' prove.

Accepting that is not only accepting immoral, perverted justice, but also accepting a statistically flawed system.
And that's just plain stupid. No morals involved.

You wouldn't accept a PC that's failing 12% of the time, but you would accept a justice system that fails in 12% of cases, and kills people in your name ?
