I do not know which bible Pat Robertson claims his authority from. However, the one I read did not portray Jesus as a vindictive bully.

The post referred to God, not Jesus, as the Bully. Now I don't know what your criteria are, but flooding the world and killing everyone apart from Noah's family, destroying Sodom and Gommorrah, turning Lot's wife into salt for having a peep, sending ten plagues to Egypt and killing all their first born, Making Abraham think he had to sacrifice his son, tormenting Job etc etc, all makes his creations in his own image, Stalin, Hitler, Bundy etc, look pretty tame.
