He owldn't be a villain. He'd be like a tragic character. Natsu and the others wouldn't try to defeat him, they'd be trying to save him from his disappear. Like, Rogue tries to kill Gray after finding out about Frosch's death, Sting intervenes, and Natsu, faced with a difficult choice, would charge at Rogue and... hug him, tearfully, saying he knows what it's like to loose someone you love. Then tells him not to let the shadows consume his heart. Then Rogue, after agreeing, pushes Natsu away, takes out his sword and stabs himself in the heart, whispering "Natsu...Dragneel...you knew...didn't y-?" before dying. And Natsu would be left after the Alvarez war, grieving, blaming himself.
