I disagree; it may have suited what he (re)designed as good, but he wasn't that far down the road to not be aware that what he did contradicted his initial mission, to not use power, but to help. He sees himself entitled to break light and tarnish white, just as he arrogated the right to renounce his mission.

What's wrong with 'corrupted' in this case? One can be corrupted by an idea just as easily as by a 'force' - perhaps more easily.

Well, because this case involves a lot of self-deceiving, convincing himself that what he does is still some type of newly defined good. It is not forced from the outside upon him (which would be the case with Gandalf struggling with the ring), but he "forces" it, to a certain extent, upon himself - as long as he has a remnant of consciousness and morality.
