A perfectly giving, kind and good-hearted person, too, can turn bitter and become an extreme pessimist — unkind, unreasonable and un-compassionate — after awhile of being overwhelmed/conditioned by hardship and especially lack of appreciation, support and love. It’s a similar negative effect in that it changes people’s conduct negatively. However, this is of much lesser resulting severity degree compared to what happened to prisoners or guards after being abused to extreme atrocity or conditioned to neglected system.
This perhaps requires more urgent attention/understanding because this type of negative transformation happens more on a regular basis in our everyday’s lives; it represents our larger population and is the very fundamental of most problems in our society.
The message from your prison experiment has conveyed my belief more vividly that good nature must be accompanied by good nurture in a consistent manner for exemplary positivity to result of any individual. Any deviation to this combination, a varying degree of negativity will result. And yes, it’s all relative and we may not notice the slight or subtle difference, unless those negative effects were of enough accumulation to be noticed. Following this same principle, I believe there is only ‘one’ way to transform criminals back to becoming decent-hearted people and that is to recondition them with and in positive and ‘nurturing’ environments. Current way of prison and punishment is not one of them and will never work. With nurturing to change, all we need is time.
