Saruman a copy-cat?

[Earendilyon]

Sarin Elfarmour, you said:

gandalf is the only wizard who acomplished his purpose (maybe radagast awell, im not sure)

According to JRRT himself, none of the wizards succeeded. I quote from Letter 156:

The 'wizards', as such, had failed; or if you like: the crisis had become too grave and needed an enhancement of power.

Radagast also failed because he became 'enamoured with birds'. Quote from Unfinished Tales, The Istari:

Indeed, of all the Istari, one only remained faithful, and he was the last-comer. For Radagast, the fourth, became enamoured of the many beasts and birds that dwelt in Middle-earth, and forsook Elves and Men, and spent his days among the wild creatures. Thus he got his name (which is in the tongue of Numenor of old, and signifies, it is said, "tender of beasts"). And Curunír 'Lân, Saruman the White, fell from his high errand, and becoming proud and impatient and enamoured of power sought to have his own will by force, and to oust Sauron; but he was ensnared by that dark spirit, mightier than he.
