As Kabbalah teaches, we all desire to be happy and not in pain; hence when we are happy, we are, well happy / open / loving, hence considerate, compassionate etc. but conversely, when we God-forbid are in pain, and more importantly when we are resentful (towards people) we then become jealous that others are not in pain, and this is the source of bullying, malice, anti-Semitism, worldwide anti-Americanism, and all radicals who pretty much hate everyone.
