the cause of all maliciousness – anger (not at the person who hurt “you..” that’s called vengeance – rather at unresolved vengeance – hence this unpleasant feeling, which makes a person feel belittled, and simultaneously angry, makes a person jealous of those who don’t – hence as the desire of jealousy is for the other to similarly suffer, and as desire controls thinking – the mind begins to a. see the evil in the other, which qualifies that b. I should belittle them.)
