What does it mean when he says don't use any physical examples just expand on the main concept. Also how is Greed related to war as a social disease and empathy.

Answer 1

Since I didn't respond to the original post, I'm not sure what you mean by "physical examples."

If you are really greedy, and you can't get what you want by legitimate means, you will use illegitimate methods — which can lead to war. Those who are greedy are not empathetic; they show little or no concern for those whose possessions they accumulate.

Greedy people are more typically aggressive rather than assertive. Assertive people are more empathetic. Possibly these two articles might help you understand these concepts.
