it is hard to imagine this theoretical situation. ******** who will be *********... without a chance to change the way they will go, it is too much incredible condition. That supposes that some kinda *extra-magic-exceptional* ability exists: ability to predict the future. but at the same time, there is no *quite an ordinary* ability to change something in the life/upbringing of that ******** to prevent them from becoming *********, already knowing their inclination for crime. That is just absurdly IMO. That is similar to the supposition, that a doctor knows that his patient has susceptibility towards diabetes, and due to that fact decides to **** him, instead of performing prophylaxis.
as for the other part of the question, I am sure that some assholes got to be ****** for the **** they had done to other people. there are such an assholes in this world, that all that progressive philanthropic charitable & whatever-else-it-can-be-called views do not stand up to any criticism!
sometimes I think that some people are just up in the clouds, talking about cancellation of capital punishment... just read some criminal chronicle of events!
So, coming back to the subj, indisputably, if I ever face that choice - to **** a bastard, or not to ****, I will do it. but only when it is about people who had already done some deadly sins, not about ******** who "will grow up to be..."
