I was thinking to include the cat burning example myself but i prefer to keep my posts simple and with no references.

Indeed, like i mentioned above, nobody wishes for someone else to suffer but it becomes a necessity due to the fact that most people in this life suffer themselves and they tend to associate this causality to the people around them.

Living is for the most part suffering and since our peers are the ones that effectively change and manipulate the world is easier to wish to someone ill -- if we somehow connect the dots that they are the cause of our own suffering
