I believe Larry Ellison uses power in an unethical manner. A good example is when Ellison blasted the HP Board of Directors for firing their CEO over allegations of sexual assault, and then hiring Hurd to work at Oracle. Ellison steps beyond business and uses personal attacks on the CEO's and Board of Directors of other companies to try to obtain a competitive advantage. Ethical business practices can be done with a hard business plan, but personal attacks and win at all costs by doing anything possible to win, constitutes unethical business practices.

I would not emulate Larry Ellison's behavior in my career. While the quest for success and power are admirable, I would not be comfortable in using the behaviors of Ellison form the combative mode against his competition to gain a competitive advantage. You can be successful by being a strong competitor and using ethical tactics to build a successful company. The other consideration is if your employees see that the CEO excels using unethical behavior or unethical tactics, then this gives the employees the implied approval to act in the same manner as your leader.
