Well, he [i]does[/i] have something else going for him. Unlike characters such as Zuko or Raphael from the TMNT, Shu doesn't have an Iroh or Master Splinter reining him in. I mean imagine what Zuko would have ended up like if Iroh never existed. That's Shu in a nutshell.

Oh I believe he will have a comeuppance sooner or later. No fire can burn too hot lest it consume itself. No earth can shake too much lest it become dust. And no wave can spread itself too thin lest it evaporate. Irohs are everywhere. When the student is ready, the master will appear.
