Yang probably was like: "Summer was a huntress and she raised me as her daughter, dad is a hunter, Uncle is a hunter and saved my life and Ruby's when we were little. My missing mother was a huntress, maybe if I become a huntress I can figure out what happened to her and be good like Summer and Uncle and understand Taiyang better."

Blake had already talked about her decision as deciding to no longer aid the White Fang and put her skills towards becoming a huntress. I think her questioning in this episode comes from that, when she made that decision she was like "All I have done all my life is fighting, so the way to amend for the bad things I have done is probably fighting because there is really no other thing I know how to do."

As for Weiss, I think she didn't lie to Oobleck, at least not downright. I have mentioned before Weiss at the beginning of this Volume was a complete different person then she was at the end of Volume 1. She went from becoming infuriated at people insinuating bad things about the SDC to forcing visibly forcing smiles when called by her last name. She went from calling the White Fang a "bunch of liars, thieves, and murderers" to calling Blake's years with them as "fighting for freedom".

So, when she made her decision of becoming a huntress, it probably went down the way she told Oobleck. But since she has arrived to Beacon things have happened that have changed her as a person. So that reason is no longer true.

Actually, I think Oobleck might not have made them question "Why they want to be huntresses" but "if they really want to be huntresses" or at least if they decided to be for themselves.
