@Docdon23 what would you call a prison cell? Yes its definitely more humane to kill killers and pedophiles, why should tax payers have to pay for them to live in a cell the rest of their life? Who advocates that? That would be president Obama, he did that to "Illegal" immigrants.
@Reverend Do your homework. It is MUCH more expensive to execute them, besides hardly being humane...societies grant rights, not life, so they can take rights away, not life.
