One of the most baffling questions to any sane person, of-course, is evil: why would terrorists blow up the twin towers when we never hurt them? why would Germans, murder millions of Jews, when if anything, we only helped them?! why would anyone harm anyone, if they did not harm, the harmer?!! the answer is simple, jealousy – people who feel down, become jealous of people who don’t; or at least people they perceive to feel up; this is why radicals hate wealthy people, notwithstanding that wealth doesn’t make you feel any better; but because in their mind, they think wealthy people feel good about themselves, therefore, they hate them – I know it’s hard to believe this, but this simple understanding, “people who feel down about themselves, hate people who don’t” (at least who they perceive, they don’t) explains all of evil!
