This is the type of ridiculous thinking that promotes child abuse. As if a well loved and cared for child will want to harm anyone. The sad truth is those who act out massive violence on others or normally themselves victims of chronic abuse and violence. So this kid is more likely to harm others, not less likely. Hope this helps.
You're right of course. I was raised without violence or any threat of force and I absolutely knew that no one was ever going to harm me physically and I still had so much respect for my parents
that I would not even dare to raise my voice against them no matter what. I was in a lot of trouble as a kid and teenager but I always knew that no matter what I did I could always
expect love and understanding which is why I hardly ever lied to my parents.
On the other hand most of my friends experienced at least some form of physical abuse during their childhood and when I saw how they behaved towards their parents I was in disbelief... they yelled at them, insulted them and even hit them back. They would go and steal from their parents, lie to them about everything, spit in their coffee... and they got just in as much trouble as I did because boys will be boys I guess
There is not only no need to ever hit a child, not even a little slap on the wrist, but it is counter-productive and possibly fucking up your kid for the rest of his life to some degree at least.
