I think  it has more to do with Blake's early childhood upbring (If she was telling the truth about that). It could be life outside the kingdoms meant that at some point you are expected to fend for yourself(You can't fight you can't survive) and while joining the White fang give her something to fight for (The promise of a better life for all fanus).That instinct of self preservation is still there,only allowing her to step in when things gets really bad.
