All men are endowed with unalienable rights, among these being life and liberty.
But you can lose those rights. He who takes another’s life loses his own moral right to life, just as he who infringes on another’s liberty loses his own moral right to be free.
Pretty simple, IMO.
BTW, I agree about the guillotine. The Bic of execution methods. Works first time every time.
Also replacing the air in the execution chamber with pure nitrogen would result in quick unconciousness and death within a few minutes.
Why a quick death for these animals. Many victims were tortured for hours, even days. And we worry about a quick painless death for them?
