Whoever wrote this letter is obviously an extremely troubled individual. It would be incredibly easy to get angry and start crying out for her to be punished for it, but decisions made in anger often lead to regret. What kind of person thinks like this woman? A miserable one. She’s being punished already simply by living her life. She won’t become a better person with the addition of more pain.
Many would say they don’t care about making her a better person. They want her hurt to make them feel better. Hurting someone else to feel better is what the writer of this letter did. She thought that somebody deserved to be put through pain, so she lashed out just like you might be thinking about doing.
But there is a difference, you might say, between them. The mother of the autistic boy did nothing to deserve punishment. The letter writer would disagree. In her judgment, the mother was doing something wrong. In your judgment, the writer did something wrong. In both cases, the answer to a crime is another crime.
Hurting other people on purpose is always wrong no matter who you are, no matter who they are, and no matter what they did. If you went back in time and punched Hitler in the face, you would be doing something bad and probably creating paradoxes for The Doctor to iron out. Shame on you. He has enough to do without you messing with the space-time continuum. Justice means dealing with people in a fair way, not hurting them so you can feel better.
In order to break the cycle of hate, you have to deny yourself the expression of your anger. Don’t scream, don’t hit a pillow, don’t fantasize about the letter writer getting her comeuppance, and don’t write an angry reply wherever you first saw this posted. Whatever you want to do, don’t do it. Take a deep breath or two and consider that aggressive words and actions are the resort of people who are already in pain, and inflicting more pain on them will do nothing but cause them to amp up the aggression. Imagine how you would feel about someone going through pain who did not behave aggressively toward others. That is how you should feel about her. She needs for the pain to stop. She needs help. The power to spread pain comes easily to those who call upon it, but the power to heal is much greater and much harder to summon. If you want to make the world a better place, show compassion for everyone who hurts. Start with yourself.
