[10,000 Volt Ghost]

Either people want to be omnipotent or they are afraid of others taking what they have. So a person who already has tons of power might become paranoid that others will rise up and take what's theirs. Said person goes out of their way to achieve more so others have less. Whenever there is opposition, one will continue to want to exceed and rise over the other/s.

Greed and fear can make for a dangerous opponent. Not only that, if you were on the other side what would you do to overcome them. Cycle repeats.
