No.
The Good\Evil axis is entirely about the distribution of power in any of it's forms, be it money, influence, knowledge, strength of arms, manpower, etc.
It has literally nothing to do with being a dick, something Good people can be as well.
Good people believe that power has to be divided among everyone. That your average Joe has just as much a right to own things and do stuff like you and it's the duty of those with more power to use in service of those with less, so they too can own some.
A Paladin visiting a small village will consider that everyone there should be allowed to own land and seed what they want in it, or own an office where they can practice any trade. Anyone imposing restrictions on that could be seen as Evil, which includes local bandits stealing the work of the peasants. The Paladin, having far more power than the average peasant, is now under the obligation to assist and protect them.
This has mostly to do with the idea that, by giving everyone a chance to do their thing without interfering and even cooperating, a lot more can be done. A fort of soldiers fights better when they don't have to farm their wheat or bake their bread, for instance.
Being Evil on the other hand is the exact opposite. It's the belief that the best person to own any form of power is you, the one that will best use it anyway. Sometimes it's for petty personnal gain and luxury so you can afford all the banquets and concubines you want. Other times, it's because you believe everyone else to be fucking retarded and what they need is a sword shoved down their torso so you can take their role and actually get shit done.
A Lord that taxes the peasants but then uses that money to fund his army and build roads is not evil. But if his family is the only one using those roads or his army does nothing but pilaging other people, he is Evil.
A Lord that backstabs everyone he meets because he doesn't trust them, is evil. But one that condems traitors to death isn't.
To put it simply:
Gathering the 6 Elemental Orbs of Power is not Evil nor Good, unless they had a Good\Neutral owner that refused to part with them, making it Evil or they were owned by someone Evil and you intend to use them for Good, making it Good.
Using the Orb of Fire to set the Warrior on flames when he's attacking you to retrieve the Orbs back is not Evil. It's self-defense.
But using the Orb of Thunder to smite the Wizard and take his spelltome for yourself is indeed Evil.
Using the Orb of Earth to wall off a town and then flood them with the Orb of Water is not being Evil, it's being a dick, an animal at best. You stand to gain nothing of this at all.
Using the Orb of Shadow to raise the drowned as an undead army to serve you however is indeed Evil. But if you used it on people you had not killed and commanded them to guard anyone Good, it would be a Good thing instead.
Using the Orb of Fire to char the local wildlife is not Evil nor Good, it's also you being a dick to the animals, unless you are hunting.
Using the Orb of Light to impersonate a religious figure and gain the trust of the population is not Evil. But if you found a dead cult to raise an undead army, that's very much Evil.
