Ilúvatar good & evil

It's 5 posts up from yours, but I'll repeat it here for your convenience

5 posts up from Arty's post, I said:
And then, further down, "it came into the heart of Melkor to interweave matters of his own imagining that were not in accord with the theme of Iluvatar, for he sought therein to increase the power and glory of the part assigned to himself." And the result of this? "discord arose about him, and many that sang nigh him grew despondent, and their thought was disturbed and their music faltered...

And even if Melkor did try to increase his own glory by altering the Great Music, can that be called evil? I don't think so, not unless the intention is to bring forth something bad, and there's no indication that that's what Melkor had in mind at this point.

Perhaps when he first started, his intent wasn't evil, but I think the fact that those around him "grew despondent" and he didn't stop shows great evil on Melkor's part

Maybe it's an English-language thing; but to me, the way it's worded, the "increase the power and glory" sentence shows that Melkor's intent was selfish ambition, and not an innocent thing at all.
