People dey always dey talk say power corrupt, power corrupt, yes most of us don talk am before, we dey think say na power dey corrupt person but the truth be say most of us already get corruption inside of us we only need the opportunity (power) to bring out the corruption in us. A man once said if you really want to know the person true self give him 3 things: Money, Power and Access to Sex. With this 3 things you can know any one true nature. So no be power dey corrupt, power only reveals corruption.
To an extent, I may seem to agree with your ascertions, but to a very large extent, I may like to disagree too. Saying this means that I believe there's no generality in what you said. Sometimes, people become tempted to power and as such they go into things they never thought they could through the influence of others. On this case, I fit talk say, the person mind been don almost they corrupt but na the opportunity to join the corruption na hin him been they lack, so as he saw the opportunity in the individuals surrounding him, or his colleagues, he grabbed it well by joining them.
Another reason why I been talk say I go disagree with you be say, there's what we call; SYSTEMIC CORRUPTION or in another words, ENDEMIC CORRUPTION, and that's the kind of corruption that happens within the weak system of an organization. Most of these corruptions take place in the public sector rather than the private sector.
In the kind of corruption, it is like a cabal or cartel system where it runs through ranks of the organization in an organized manner mostly orchestrated by the top officials or the government in itself to loot out funds from the organization. You don't need to have intentions to be corrupt before you're drawn into it, especially when you get promoted to such ranks. This time around it's not an individual thing and it in such cases that you're given the thin option to join the system or resign with immediate effect in the event that you refuse or frustrate the syndicate.
