Sometimes people that were bullied during their childhood tend to continue to have emotional insecurities deep into adulthood. Such insecurities can manifest themselves in repression or an inability to feel certain emotions that by itself, in the end, can lead to one bitter existence, with the need to punish others for something that they never did. This self-repressing can be the cause of why some people seem to only want money, sex, power or fame.
Such drive on its own doesn't have to be negative, per se, but it can be devastating when applied and directed towards a person that has or expects an emotional bond with you. If you yourself tend to feel anger every time someone says no to you, then you must learn to appreciate and express your own emotions as well as the emotions of other people. In other words, most conflicts can be resolved by simply talking, but only if both partners are willing to resolve the issue.
