Wouldn't maturely tackling such deep issues shift a story away from the shounen genre into something else?

FMA and Magi are actually pretty good examples of this, since they both already scratch the borders of their genres. Some might (and do) even argue that they actually are something more mature with a few shounen elements, rather than being actual shounen manga.
