I guess it only applies partially to him, but even he didn't finish off Natsu, Gray, Lucy and Happy because he had something more important to do.

Also instead of just going on a destruction spree, he sealed himself up so that he could forumlate and follow a bigger plan in the shape of Brain.

While his ultimate goal was the destruction of everything that has form, he still went about it in a way that for me puts him way above many two-dimensional villains in other series (not limited to anime and manga).
