Just my opinion: Not all power corrupts the human mind. If you use the power to heal sick people (a doctor), that is not corrupting. If you use the power tg make people do things that can be corrupting. For example dictators have the power to make people serve their harmful wishes. This is corrupt. A dictator could start using his power over people with only good intentions. But there is the strong temptation to use it in a manner that is harmful to others. So to me power over other people, to make them obey you, can be corrupting.

The question itself is on the fence, on the one hand, if a person has a low emotional quotient, then he/she may be easily get corrupted by power. On the flip side, if the emotional quotient is strong, or 'mentally strong', let's say, then this influence would not muscle in his sanity. Is it clear?
