the only thing I can TRULY remember him doing for himself is Gael.. (for those that aren't on Season 3, I will go no further with that).. even that "could" be construed as for both himself and Jesse
everything else started off as being for someone else (as twisted as it may seem).. the start of the whole thing was for his family.. allowing what happened to Jane happen was more for Jesse, as was what he did at the end of season 2 with the two "enforcers" (also for Jesse) as well as trying to keep the money away from Jesse (afraid he was going to spend it all on drugs)
i think the Skyler is more about herself than Walter is.. havent really been a fan of hers ever since the show started.. also dont like where Hank is headed.. become a right nasty bastard (and I HATED his wife the first season and a half, and im feeling sorry for her)
