Torture is the most vile act a human being can commit, and should result in perpetrators losing all rights they have as a human being. I think some people are quite glib when the subject comes up. Anyone who doesn't have enough creative impulses in their brain to fill their time productively, and feels the best way to overcome their boredom is to put the kettle on, and then inflict as much pain and suffering as they can on another creature...I dunno.
I mean, when I'm really really bored I play chess titans on the computer. What worth is a human being to society when their chimpanzee brain decides torturing rats with boiling water is a good idea? I know people commit heinous crimes for all sorts of reasons. Insult, revenge, money etc. But to actually decide your gig in life is to take an innocent person or animal, and then cause them as much prolonged and unnecessary agony and misery by whatever means your mind comes up with, for no other reason than personal amusement...people may think I'm overreacting but personally, I wouldn't even waste money locking them up. Straight to execution.
