I don't want or need some one to dive with me who is unwilling to state something is a bad idea, they aren't feeling it, or the plan is beyond their comfort/skill level.
If you are diving with people that you are too afraid to tell them you are uncomfortable with a dive plan or that something during the dive has made you not want to be there then you either need to suck it up, find different people to dive with, or come to the realization that you just may have no business making technical level dives.

That is actually the most important point concerning this dive (not the whole story with involves legal issues, truth and lies and liabilities).
Let me tell a story about a tech dive which is very related to this incident.
We planned a dive of 20 minutes to 60 meters (which is just shy of 200' for those non metric inclined) on the Loredan wreck (in gulf of Cagliari sand is at 62 meters top of the wreck at about 55). We had TMX 18/45 as back gas EAN50 and Oxy as deco gasses).
While descending @20meters/min my buddy tells me he has equalisations issues: nothing new - fast descends aren't his bread and butter so we stop he clears we continue. We get on to of the wreck vis is about unlimited (30 meters about 100') so we get a bit of space between us (we are both solo cert and happy with solo diving). But we are a team so we keep looking to each other and I notice he has bad trim. I rejoin him and ask him if he has problems. He let me understand he cannot find the horizontal.
Big alarm bell goes off, we are 10 minutes into the dive, we have racked up substantial deco obligation and my buddy cannot orient himself. I thumb the dive and we ascend together to 24 meters ready to switch EAN 50, I pull out my wet note we exchange a few ideas recalculate our deco schedule and decide to stay on EAN50 all the way to surface to avoid additional risk with Oxy in case he cannot hold the 6 meters stop.
He had suffered alternobaric vertigo and the he was diagnosed with an issue in the middle ear (polyps) and a possible labirynthitis he took about one year and half to fully recover.
Bottom line he dove with a medical issue he was not aware of, but when it was manifest he had an issue he came forward and clearly indicated he had a problem. If he just had thumbed the dive and told me it was ok to be left alone, I most probably would have kept my dive plan and kept exploring the wreck.
Instead he had an issue and we carried out the abort as team. Things is, we are habitual buddies and we know each other, we recognise style and attitude, we also brief extensively. Instabuddies need to talk way more and be truthful with their team/mates in order to receive their support (or even to le them decide to allow to be part of the newly created team).
At the end we (as individual or team) cannot do proper risk management if the risks are not acknowledged first. Ignore a medical psychological, stress, alcohol, emotional issue does not do any good to the diver or his team.

p.s. Loredan is a great wreck and I went back several time (albeit with different team) after that dive:
