Eru gave Melkor the choice to be who he wanted to be, a part of Eru's realm (heaven) or his own master in the void. Melkor chose the void.

Guys, read Tolkien's letter on the Silmarillion. It is clear as day that he intended Eru to be the Christian God (He even calls him such in his letters), and, as such, Eru is good, all good, and, in fact, he is goodness itself. Tolkien was a devout Catholic, and his works express this (Not that non-Catholics or non-Christians cannot enjoy his works, but he does have some good theological insights for Catholics)

As I have already said, Tolkien made the lore, not us, and what we believe does not affect this.
