Vinny being responsible for literally anything that has happened with the DIKs woud be an honest-to-God asspull of a plotline, even worse than the fire and psycho Leah.
The guy has been expelled from B&R, likely for getting caught dealing drugs, and maybe the DIKs weren't much help to him because they didnt wan't to get taken down with him, but the idea he would come back on to campus, break in to the mansion, gain access to the laptop, and post a naked picture of Cathy to get the DIKs in trouble is ridiculously lame. So too is the idea that he sent pictures to Chad, or he trashed the DIK mansion, or that he has someone like Nick helping him, because really, what's the point? To bring down the DIKs because they maybe didn't stand up for him? What actual good would that do? How pathetically petty is this guy? So they don't have a frat anymore, big deal, unless they were accused of doing something as bad as or worse than dealing drugs, they'd all still be able to stay at the college and finish their degrees, so not having a frat doesn't hurt them that much.
The whole "Vinny villain" theory in this context is weak sauce and he'd be a pretty pathetic bad guy character if this is what his role is.
