If someone does something that is perceived as wrong then they tend to be punished. In the case of children, this punishment is usually administered as a form of discipline, teaching the difference between acceptable and unacceptable behaviour. They aren’t punished because of the thing that they did wrong, but because they are being shaped and moulded into the person that their carer wants them to be; it’s an act of love, or at least it should be. Most legal systems work on slightly different principles – their punishments are based on retribution, deterrence and rehabilitation.
People make snap judgments about almost everything, it’s a perfectly logical natural instinct that prevents you from coming into contact with the same bad thing twice and, equally, leads you to do something pleasurable again and again until you lose interest. I am of course making an overgeneralisation and oversimplification of something that’s influenced by a number of other factors but the principle remains. I know this because I do it myself all the time, we just can’t help it. A good way of testing this point on unsuspecting individuals, provided they are in a talkative mood, is to ask them about their recent holiday destinations, provided they’ve recently been on holiday. You’ll find people saying things like “Oh yes! ‘insert-country-here’ is a lovely country, beautiful scenery, the food’s not too great though,” despite having visited the capital city for just four days, eating at the hotel restaurant every night and visiting two museums and a temple.
