I am not sure that Ancient Greek Gods actually started any wars, but it has to be pointed out that states would not go into war without the consultation of an oracle to see if they have the support of the Gods (to win the wars, as the Gods were responsible for everthying)
No the Greek gods were not "grumpy". In fact, most of them were quite cheerful. However, they tended to take sides in mortal wars. It is believed that in WW2 the Greek gods took sides. They don't fight in the mortals' wars, but they start their own wars with each other because they disagree about who should/will be victorious in the mortal wars. In general though, the gods were not grumpy. They merely had minor discrepancies that caused anger and irritation occasionally leading to wars.

he is bloodlust, determined, vicious, cruel, and brave and hunger to kill and make the other greek gods have wars.
Some believe that they did get involved in mortal wars. One legend is that Ares possessed Achilles, the great Greek hero. If the gods got involved in war, they tried to assume a mortal form, sometimes of a great hero.
