Patrick admitting to killing Bernell Tyrone:
The most compelling piece of "evidence" suggesting Pat killed Bernell is that AFAIK when confronted about it via text or Xeeter, he has never "no child I did not murder Bernell Trammell, those are your delusions." He chooses to ignore it. This goes against all the fundamentals of Patrickism.
Patrick is a FFWBT so there are many people who can't see him harming, let alone killing, anyone for real, but I am of the opinion he
is capable of that. And no, that doesn't make him some kind of a badass (like he might think) so I'm not complimenting him. It would have to be him snapping while intoxicated or something like that. Patrick has many hallmarks of those family annihilator men that kill their family because all their lies caught up to them (Christian Lango), they've become a hinderance to his goals (Chris Watts), and/or they have become a thread to their delusion (John List).
Some might argue that Patrick's comment about killing Ade and unborn Pat Jr. was something made in the heat of the moment and he didn't actually mean it.
This is part of the "point" in 12 Angry Men. Fair enough, but I would be more likely to believe that if he only said that about Ade, and did not also threaten to kill his own, innocent child who was still cooking in the oven. He also must've said it in such a way it genuinely frightened Ramona instead of her just saying, "Oh Patrick, I know you feel bad but don't say that."
