Is Zeus a good person

It depends on your definition of 'good'. Zeus was the major domo of the gods, and thus the Greeks also viewed him as such. Would they have an evil guy as their supreme ruler? Probably not, unless such a rule was forced upon them. Zeus defeated the titans and paved the way for the rule of the gods on Mount Olympus. He also, according to some legends, ordered the creation of mankind (an order which Prometheus carried out). I would assume this to be a plus for mankind in general. That being said, Zeus did an awful lot of things that he should be less than proud of. These include numerous rapes and seductions, adultery, cheating, and fits of temper (one in which he threw Hephaestus off of Mount Olympus for being hideous). Is Zeus a good guy? Well, that's up to you, but it is probably safe to say that he wasn't evil. He is simply a reflection of mankind.
