Anger is the wish to harm another being. The conditions for real anger are that
– I know you are a human being,
– I don’t like you and I want to harm you,
– I do it or have it done,
– and afterwards I am satisfied with it.
This is real anger. To blow up and make a mistake is a very ordinary reaction, but the clear intention to want to harm someone is not present.
Most people let themselves be provoked by something and then act in a thoughtless way, but not with the conscious intention to harm others.
