[LOTR] Is Morgoth/Sauron evil or just different?

Without getting too philosophical, I would like ask that question. When Eru created the universe Melkor kept interrupting and creating a different song that wove into the pattern.

Isn't it likely that Melkor merely perceives an anti-creation and that he can't comprehend or support the designs of Eru? His works look revolting to us because we are of Creation and it's built into us, but perhaps Melkor, Sauron and friends have a perpetual inner feeling that this is not what Creation should be and they do everything in their power to destroy and redesign it.

It's an interesting question to ask. I'd say as far as the individuals are concerned, it probably doesn't matter much. Say Ungoliant was just doing what came naturally when she devoured the Two Trees of Valinor. Probably doesn't really comfort the elves who've had the lights of their world destroyed (for a second time). Overall, I'd say it's not really Melkor's works that are the problem, but his destruction and corruption of the works of Valar, Maia, and Elves.    
  
If you want to explore a similar concept, The Last Ringbearer is a Russian work (since translated into English) that looks at the War of the Ring from the perspective of an Orc soldier, and turns the typical moral compass of the world around. Really good read.
