How can God feel jealous?

Sometimes I wonder how can God have feelings of jealousy and pride in him?I am not talking about the devtas like Indra and his group. I am talking about kartikeya.How can he have jealousy for his younger brother and proud of his strength? Aren't Gods above all these bad qualities? If they too feel jealous and proud like humans then what's the difference between Gods and humans?
Or is it part of their leelas to teach mankind a lesson that u shouldn't feel proud of ur strength and underestimate ur younger siblings?

Even Bramhadev was proud and arrogant-so much so that he lied about him finding the end of the Shivling to prove his superiority to Vishnu

Maybe it's a leela to show the right path so, that mankinds will follow this , aise hi toh peacefullness ke subh arambh honge 😃.

Even Gods have their shares of family dramas 😆 Just kidding.. Such stories are meant to teach us lessons.. 😊

Arrogance is due to lack of correct knowledge. Ganesh found the deeper meaning of the Pradakshina challange & found the answer which respected his parents, who are Jagat pita & mata, means the entire World for a child. This incident proves his ability to see, judge a situation from different perspective. Where as Kartikeya took it as only doing pradakshina of the Earth. Their approach to the same challange was different, which proved Ganesh is smarter then Kartikeya.

Even if we keep the human emotion aspect aside in case of Gods, it's approach to the same situation proves who is greatest.
