You're missing the point entirely.
The fact that he could blow that building in place because he has
1. The technical know how
2. Easy access to the necessary information and materials necessary
3. A history of harsh violence
4. An assumed (by Chuck and Kathleen at least) dark sadistic personality
5. Youthful lack of future forward thinking
All of that makes him someone you don't just fuck with for shits and giggles if you are as smart as Chuck and Kathleen are supposed to be. The fact that he has done zero zilch nada thus far means he isn't doing shit no matter what Victoria reveals or keeps to herself. That is the point I'm making. He's sold his soul for tuition. Victoria's situation is a nice cliffhanger and little more.
Chuck isn't really messing with the MC as much as he seems to be trying to guide him and possibly make amends. He warns Kat about going too far with the Rose porno scene to the point of an implied threat to Kat about him being like family. As we don't quite know the history between Chuck and Victoria yet, we can't truly say what happened. Did Chuck sit in on one of Don's movie shoots and see Victoria? Was this before or after Ian and Edwin met? Maybe he saw her at a filming or in a movie and later met her as Ian's BF's mom/person Ian looked up to as a mother and helped her/convinced her to get away from doing porn. Until we know for sure what the past is between them we can only speculate.
TBF your overlooking the fact that this could be a catalyst for him helping/siding with Van Doren to take down the Club's leadership. We've already seen the in home meeting where VD warns him, maybe this could be the factor that pushes him to align with them to remove the current leadership. They have the resources and are already working on their plan. Remember it's not the club he would want revenge on it's the people responsible, taking Kat and Chuck(if he had a negative hand in Vic's past) out of the picture somehow (not killing but destroying their reputations/lives) would be a fitting revenge. You can add others along the way who are involved like Warren with Kat and maybe Grace with Chuck just to tie up other loose ends. This is all just speculation but if Edwin wants to get revenge on Kat and Chuck siding with VD would help him out immensely.
BTW the tuition deal was from Chuck not from the club. The deal is to work for the club and Chuck will pay his tuition. This has a multiple purposes: getting Ian back with a "good" influence, helping out the club(replacing the "missing" guy), letting the MC explore his wilder desires and getting "life experience". Not to mention banging all the hotties along the way. So knowing that in theory, if Kat pushed the MC too far and he left because of that, Chuck could still pay for his tuition if he chose to. Not saying he would just that he could.
