The death penalty in itself, is NOT a deterant to committing crime. Most criminals don’t give a $h!t what happens to them if they get caught. The penalty is just that, a substantial penalty for a substantial crime. I do believe that when capital punishment is removed, it minimizes the crime. And that is exactly what humanists (liberals) do. They want to trivialize and minimize everything. It is part of their moral relativism campaign.
And yet certain other “wrongs” (often things that weren’t even “wrong” till they came around) get the execration treatment.
