Much like all the Celestials, Eson was an extremely ruthless, destructive and megalomaniacal being possessing a god complex.
He willingly used an Infinity Stone to destroy an entire planet presumably with little concern for the inhabitants on it. It is possible that he may have wanted to reshape the planet in his image, like the other Celestial being Ego, which wanted a similar goal, but to do it universally.
Eson, appears to be an intelligent individual, who knew how to wield the Infinity Stone to destroy a planet he arrived on without harming himself. He thought very little about the lives of the people he killed during the destruction. He appears to think only of himself, making him an extremely selfish and arrogant individual.
