How does wolf form work in this situation?

[area]

Hello,

I have a question about a situation my friend is in. He can wolf form himself in an area where normally mobs are scowling without ever having killed one of the mobs. In wolf form he is dubious to the mobs. Killing the mobs gives bad faction hits to those same mobs (obv!). The question is, if he kills enough mobs in this area will his wolf form stop taking him to dubious (down to threateningly, then scowl again)? Or does wolf form take him to dubious regardless of how many he has killed?

Thank you for any insight. My searching on this matter was lacking either in my search skill or in results based on that skill.
