Again, I am not saying Quinn or whoever didn't contribute to pissing Vinnie off, but choosing to kidnap Rio is all on Vinnie. It was his choice. He may have felt driven to it, but he still could have chosen to not do it. I may want to bitch slap my neighbor because he keeps parking his car on my property, but I choose not to do it. If I kidnapped his dog, would I be justified? Would my neighbor have any culpability in my actions? Was any of it his fault? No. I chose to kidnap his dog and it was all on me. Period.
Don't get me wrong, the vast majority of the blame lies on Vinnie. But I think you're example is a bit of a false equivalence.
Quinn knows Vinnie is dangerous. She likely has reason to suspect that her actions could provoke a disproportional response. But she chooses to take those actions anyways despite the risks it creates (perhaps partially for the benefit of the others that work for her, but certainly significantly for her own benefit). And she doesn't share this with Rio or the others.
So while Vinnie may hold most or all the blame for the actual kidnapping, Quinn has some blame for putting her people
at risk.
It's like if I decided to drive my friends through sketchy alleys at night to buy some drugs without letting my friends know why and we get mugged. Obviously the muggers are the main ones to blame, but people are still going to be wondering why the hell I didn't stick to the safer streets.
