Killing is wrong at the end of the day, The prisons don't work though & never will, They don't improve society either they go in petty criminals & come out hardened criminals. The Colosseum had a holding cell that was the prison in early society & it didn't even rehabilitate them then with being fed to the lions as a deterrent.
In all the years of democratic voting we have never been able to elect an official that has done anything other than feather their own nest & divide & conquer the people.
We vote for the house of commons not the house of lords, only the lords pass laws.
We don't have a say the Lords make the agenda the commons make a manifesto each that has to fit that agenda, this creates the illusion that we have a choice. the human race have been in bondage to it's masters forever, the only thing to change since ancient Egypt is the masters got more crafty about how to sell it to us.
The only way out I see is anarchy, of course they have their daggers into that & have convinced us that we can't be trusted or trust each other to do a decent job. That has us convinced that it's much better to trust them to do it for us. The thing is it's them with the previous misdemeanors.
